What a petrol brushcutter is, and how the picks differ
A brushcutter is a whipper snipper with more engine and a shaft strong enough to take a metal blade as well as a line head. That's the difference that matters on a big block. Line trims grass along fences and edges, while a blade takes down long grass, lantana regrowth and woody weeds that would snap trimmer line in seconds. All four picks are petrol machines from 52cc to 65cc, which is serious engine for a garden tool, and the right size for a big block or a few acres.
The Baumr-AG 65cc Brushcutter is a straight shaft cutter with bull-horn handles, the shape most people picture. The MTM 62cc 7-in-1 has the same bull-horn layout and comes with a pole hedge trimmer and a line trimmer attachment. The Baumr-AG SMX920 is a 9-in-1 multi tool, an engine and shaft that takes a pole saw, hedge trimmer, line trimmer and brush cutter. The Giantz 52cc rides on a rear wheel, which takes the weight off your arms on flat ground.
I've left out the cordless trimmers that fill the top of Amazon AU's String Trimmers category. They're good tools for a suburban lawn, and our cordless hedge trimmer guide covers the battery side, but none of them carries a blade through thick scrub for an hour the way a 60cc petrol engine does. If your yard is a quarter-acre block with neat edges, battery is probably the better buy, and you won't need to mix fuel.
I've also left out the four-stroke trimmers. The four-stroke trimmer I found came from a seller I couldn't confirm as an Australian retailer, and a small engine you can't get serviced or warrantied here is a poor buy. Two pole multi tools from MTM didn't make it either, because their listings don't say which nine or seven attachments come in the box. Baumr-AG, MTM and Giantz are all sold by Amazon AU or an Australian storefront, and two of the four listings state a 12-month warranty.
Two-stroke fuel, the mix and E10
The Giantz listing says two-stroke, and the other three listings don't say, though MTM's own 62cc pole tools are listed as two-stroke and a 60cc-class trimmer engine almost always is, so confirm it in the manual before the first tank. A two-stroke has no separate oil sump and gets its lubrication from oil mixed into the petrol. Run it on straight petrol and it'll seize within minutes, usually scoring the piston and cylinder so badly that the engine is scrap. None of the four listings states the mix ratio, so read the manual before the first tank, and mix in a marked fuel can rather than guessing in the tank itself.
Use fresh unleaded and a two-stroke oil made for air-cooled engines, not outboard oil, and mix only what you'll use in a month or so. Mixed fuel goes stale, and stale fuel is behind most of the starting faults on small engines. Most small-engine makers say to avoid ethanol blends above E10, and plenty say to avoid E10 altogether, because ethanol pulls in water and breaks down rubber fuel lines. The manual for your machine is the one to follow.
Label the can with the date and the ratio, keep it out of the sun and never store it in the house. A fuel can that's been in the shed for a summer is often why a brushcutter that ran fine in autumn won't start in spring. If you're not sure how old the fuel is, tip it into the car's tank in small amounts or take it to a council chemical drop-off, and start the season with a fresh mix.
Why carburettors gum up, and how to stop it
The carburettor is the part of a two-stroke that fails most, and it nearly always fails the same way. Fuel left in the bowl and the tiny jets evaporates over a few weeks and leaves a varnish behind, and that varnish blocks passages finer than a hair. The engine then won't start, starts and dies, or only runs with the choke on. Both Baumr-AG listings mention a direct-air-injection carburettor, but no carburettor is immune to old fuel.
The fix is mostly habit. If the brushcutter is going to sit for more than a month, either run it dry or drain the tank and run the engine until it stops, so there's no fuel left in the carburettor to go off. A fuel stabiliser added to the mix helps if you can't drain it, but draining is better. The in-tank fuel filter on the end of the pickup hose costs little to swap and is worth replacing every season.
When a carb does gum up, a clean and a new diaphragm kit usually brings it back, and on these machines it's a job a handy owner can do with the manual and a can of carb cleaner. The Baumr-AG SMX920 listing mentions easy service access to the engine, filters and spark plug, which helps. If the primer bulb has gone hard or cracked, replace it at the same time, because air leaks there stop the carb priming properly.
The other part to keep an eye on is the air filter. A brushcutter throws up dust and grass clippings right next to its own intake, and a clogged filter makes the engine run rich, smoke and lose power. Tap it out after every couple of hours of use, wash a foam filter in soapy water and let it dry, and replace a paper one when it's grey. A dirty filter is the easiest fault to prevent and the one most often ignored.
Line heads, blades and what each one cuts
The cutting head decides what a brushcutter is good at. A line head spins nylon line and is the right tool for grass along fences, around trees and on edges, where a blade would chew bark or bounce off the bricks. A metal blade, usually a three or four tooth grass blade or a toothed saw blade, is for long grass, thick weeds and woody regrowth up to finger thickness. The MTM listing mentions a range of blades for small bushes and undergrowth.
Swap to the blade only with the blade guard fitted, and keep it well away from wire fences, rocks and the garden edging. A blade that hits a star picket can kick the whole machine sideways, and a chipped or bent blade is out of balance and shakes the shaft and bearings. Check the blade nut every time you fit it, and replace a blade with a crack in it rather than trying to straighten or file it.
Line wears fastest against concrete, brick and fence posts, so feed out short lengths often rather than running a long length hard. Use the line thickness the manual specifies, because thicker line than the head was made for makes the engine work harder and overheats the clutch. The Giantz listing describes a cutting saw blade and calls it suitable for thin trunks, heavy grass and low grass, which is the job a wheeled cutter is built for.
Bull-horn, loop handles and the wheeled option
Handle shape changes how tiring a brushcutter is. Bull-horn handles, like those on the Baumr-AG 65cc and the MTM 7-in-1, let you swing the cutter side to side from your hips with a harness taking the weight, which is how you clear a big area for an hour without wrecking your arms. A loop handle is lighter and more nimble for trimming along edges, but holding a heavy 60cc engine on one with your arms gets old quickly.
The Baumr-AG 65cc lists a patented anti-vibration system, and that matters more than the engine size on a long job. Two-stroke engines vibrate a lot, and that vibration goes straight through the shaft into your hands, so a machine without isolation mounts leaves your hands buzzing after twenty minutes. Wear proper gloves and take regular breaks, and if the vibration gets noticeably worse, check the blade or line head is sitting true before carrying on.
The Giantz 52cc takes a different approach, with what its listing calls a well-balanced auxiliary rear wheel. You push it rather than carry it, which suits flat paddocks, big lawns and long driveway verges. It's less use on a steep bank or in a narrow garden bed, where you need to lift and angle the head. If most of your cutting is flat and open, a wheeled cutter is easier on the body, and it's the lowest-priced of the four picks.
Multi tools: one engine, several attachments
A multi tool is one engine and drive shaft with interchangeable attachments that click in at a coupling halfway down. The Baumr-AG SMX920 takes a pole saw, a hedge trimmer, a line trimmer and a brush cutter head, and the MTM 7-in-1 comes with a pole hedge trimmer and a line trimmer. For a property with long grass, a hedge and overhanging branches, one engine to maintain beats three separate machines, and the attachments store in a lot less space.
The coupling is the weak point, so it's worth looking at how each one is described. The Baumr-AG 65cc brushcutter and the MTM 7-in-1 both list commercial quick-change couplings with dual floating bearings, and the 65cc lists multi-attachment compatibility. Keep the coupling clean and dry, push each attachment fully home until it clicks and tighten the knob properly, because a coupling that's half engaged wears its splines quickly and starts to slip under load.
The trade-off with multi tools is weight at the far end. A pole saw or hedge trimmer on an extended shaft puts a lot of strain on your arms and back, so take it slowly and keep the head low until you're used to it. Our garden chipper guide covers what to do with all the branches once they're on the ground, and a chipper and a multi tool together clear an overgrown corner in an afternoon.
Gear, noise and flying stones
A brushcutter throws whatever it hits, and stones, sticks and bits of wire can come off the head fast enough to break a window. Wear safety glasses or a face shield, ear muffs, long pants, gloves and boots every time, and clear the area of rocks, toys and hoses before you start. Keep people and pets at least 15 metres away, which is the distance most manuals give. The Baumr-AG 65cc listing says it comes with a bonus safety kit.
Two-stroke engines are loud, and noise rules for garden power tools apply in most council areas, usually limiting use early in the morning and late in the evening, with tighter hours on weekends. Check your local council's hours before a Sunday morning start. Ear muffs aren't optional either, because a 60cc engine at arm's length for an hour is loud enough that every manual I've read tells you to wear them.
Keep your phone out of the danger zone too. A phone in a back pocket takes a lot of vibration and sweat, and one put down in the grass is easy to run straight over with a blade or hit with a flicked stone. Leave it on the back step or in a zipped pocket. If yours has already met a stone or the blade, our Erina phone repair team can check whether it's just the glass or something underneath.
Starting, servicing and storing for winter
Starting a two-stroke is mostly about following the sequence in the manual. Prime the bulb until fuel shows, set the choke, pull the cord in short firm pulls rather than one big yank, and move the choke off as soon as it fires. The Baumr-AG 65cc and the MTM both list easy-start systems. Flooding is the usual reason a warm engine won't restart, and it clears if you leave the choke off and hold the throttle open while you pull.
Servicing is simple and mostly yours to do. Clean the air filter often, check the spark plug every season and replace it if the electrode is worn or sooty, grease the gearbox at the head if the manual calls for it and keep the cooling fins clear of grass. A brushcutter that's started to run hot or lose power after an hour usually has blocked cooling fins or a clogged filter, both of which take five minutes to fix.
Before winter, drain the fuel or run it dry, clean the whole machine, take the blade off, oil any bare metal and hang it up off the floor. Store it somewhere dry, away from the house and the gas bottle. If you also run a cordless blower or mower, our cordless leaf blower guide covers how to store those batteries over the same months. A petrol tool stored properly over winter usually starts on the third or fourth pull in spring.

Baumr-AG 65cc Brushcutter Whipper Snipper Multi Pole Tool
ASIN B075XR6YTN • $239 • Ships from Amazon AU
The Baumr-AG 65cc Brushcutter is the straight brushcutter of the four picks, and it's the one I'd buy for a big block with long grass and scrub. Amazon AU sells it for $239, and it ranks #41 in Amazon AU's String Trimmers category, #13,288 overall on the site. The listing gives a 65cc commercial engine with 4.1HP peak, a patented direct-air-injection carburettor, bull-horn handles, a patented anti-vibration system and an easy-start system. The shaft is a 26mm gold-anodised alloy pole, and the part number is a 93-prefix barcode, the Australian GS1 range, which fits a brand sold here. Amazon AU is the seller, so a return or a warranty claim goes through Amazon's own process rather than a marketplace storefront.
Of the four picks, it has the fullest listing, and it states a 12-month Australian warranty, says it exceeds Australian and New Zealand safety standards and lists CE and SG certification. It comes with a bonus safety kit, though the listing doesn't say what's in it, so check the box before you assume there's a face shield. The commercial quick-change coupling with dual floating bearings means it'll take other attachments, which the listing calls multi-attachment compatibility, so you can start with the brushcutter and add a hedge or pole saw head later. Check that any attachment you add is listed as compatible with this coupling, because couplings that look alike don't always share a spline, and a head that's slightly off wears both ends.
The listing doesn't state the fuel mix, the tank size or the weight, and 65cc is a lot of engine to hold, so budget for a good harness if one isn't included. Keep the air filter clean, drain the tank before it sits for winter and swap the in-tank fuel filter each season, because the carburettor is what fails first on any two-stroke. Grease the head gearbox as the manual says. Keep a spare spark plug and a roll of the right line in the shed, since those are the parts you'll want halfway through a job. For clearing long grass and scrub on a big block, it's my pick.
Honest caveats: The listing doesn't state the fuel mix ratio, tank size, weight or what the safety kit contains. A 65cc engine is heavy and loud on bull-horn handles, so you'll want a harness, ear muffs and breaks on a long job. Check the fuel type in the manual before the first tank: a 65cc trimmer engine is normally two-stroke, and straight petrol would wreck it.
Best for: Owners of big blocks who want a straight 65cc brushcutter with a stated 12-month Australian warranty.
Price: $239 (Amazon AU) • Engine: 65cc petrol, 4.1HP peak stated • Handles: Bull-horn • Shaft: 26mm alloy pole • Vibration: Anti-vibration system stated • Coupling: Quick-change, dual floating bearings • Warranty: 12 months Australian stated • Part number: 9348948011131 • Rank: #41 in String Trimmers (Amazon AU), #13,288 overall

MTM 62cc 7-In-1 Brush Cutter Garden Multi Tool with Pole Hedge and Line Trimmer
ASIN B075XRB8P3 • $189 • Ships from Amazon AU
The MTM 62cc 7-In-1 is a bull-horn brush cutter that doubles as a multi tool, and at $189 from Amazon AU it's the lowest-priced way into a 60cc class machine of the four picks. It ranks #84 in String Trimmers, #27,342 overall. The title says it includes a pole hedge trimmer and a line trimmer attachment, and the listing mentions a range of blades for small bushes and undergrowth, a commercial quick-change coupling with dual floating bearings, ergonomic interlocking controls and an engine housing built to take day-to-day knocks. The part number on the listing is V219-PLTM71MTMA7C0, and Amazon AU is the seller, which keeps a return simple if a part is missing from the box.
The coupling is the same type the Baumr-AG 65cc lists, so the attachments click into the shaft halfway down, and that lets one engine do the edges, the long grass and the hedge. The listing describes a patented easy recoil starting system, which helps on a cold morning. It's a good fit for an owner who wants a brushcutter first and a hedge trimmer second, without buying and maintaining two separate petrol engines. The listing calls it 7-in-1, but the title names only the hedge and line trimmer attachments, so check the box contents against the manual when it arrives. The bull-horn handles on the base unit mean it swings like a full brushcutter rather than a loop-handle trimmer.
The listing doesn't state a power figure, a warranty, the fuel mix or a weight, which is a lot less than the Baumr-AG listing gives. Ask the seller about warranty before you order, and keep the receipt. Treat the coupling gently: push each attachment fully home and tighten the knob before you start the engine. Drain the fuel before it sits, and clean the air filter after every couple of hours. Keep the blades in a box with the guard and the spanner so nothing goes missing. For a mixed garden job on a tighter budget, it's the pick.
Honest caveats: No warranty, power figure, fuel mix, tank size or weight is stated on the listing. The title calls it 7-in-1 but names only two attachments, so the full box contents aren't clear from the listing. The coupling needs care to stop it wearing and slipping.
Best for: Gardeners who want a bull-horn brush cutter plus hedge and line attachments for the least outlay.
Price: $189 (Amazon AU) • Engine: 62cc petrol • Handles: Bull-horn • Attachments: Pole hedge trimmer, line trimmer named • Blades: Range for small bushes stated • Coupling: Quick-change, dual floating bearings • Warranty: Not stated on the listing • Part number: V219-PLTM71MTMA7C0 • Rank: #84 in String Trimmers (Amazon AU), #27,342 overall

Baumr-AG SMX920 65cc 9-In-1 Long Reach Garden Multi Tool
ASIN B075K7MVVN • $339 • Ships from Amazon AU
The Baumr-AG SMX920 is the multi tool of the four picks, and the one for a property that needs a pole saw and a hedge trimmer as well as a brushcutter. Amazon AU sells it for $339, and it ranks #17 in Power Hedge Trimmers, #9,661 overall, which is the best overall rank of the four. The title says it includes pole saw, hedge trimmer, line trimmer and brush cutter attachments, and the listing describes a commercial 65cc engine from Baumr-AG's Pro-series with a patented direct-air-injection carburettor and a balanced design. The model code on the listing is SMX920, and Amazon AU is the seller. Amazon files it under hedge trimmers rather than string trimmers, so the overall rank is the fairer comparison with the other picks.
The feature I'd buy it for is the easy service access to the engine, filters and spark plug the listing mentions. On a two-stroke, the jobs you'll do most are cleaning the air filter, checking the plug and getting at the carburettor, so a layout that makes those quick is worth more to me than another attachment. One 65cc engine running four heads also means one carburettor to keep clean and one fuel can to mix, rather than a separate petrol engine for every job in the shed. Hang the attachments up with their covers on, because a hedge blade or saw chain left loose in a box gets knocked and dulled, and keep a bottle of bar and chain oil with the fuel can for the pole saw head.
This listing doesn't state a warranty, the fuel mix, a weight or the shaft length, so ask before you buy, even though the Baumr-AG 65cc brushcutter listing states 12 months. A pole saw on a long shaft puts a lot of weight at the far end, so start low and slow, and keep the coupling clean so the attachments stay tight. Check the saw chain tension before each use, because a loose chain on a pole saw can come off the bar. Drain the fuel before winter. For one engine that handles grass, hedges and branches, it's the pick.
Honest caveats: The listing doesn't state a warranty, fuel mix, weight or shaft length, and its feature list is short. It ranks in Power Hedge Trimmers rather than String Trimmers. Long reach attachments put a lot of strain on your arms and back.
Best for: Rural and big-block owners who want one 65cc engine to run a brush cutter, line trimmer, hedge trimmer and pole saw.
Price: $339 (Amazon AU) • Engine: 65cc petrol, Pro-series • Attachments: Pole saw, hedge, line trimmer, brush cutter • Carburettor: Direct-air-injection stated • Service: Easy access to engine, filters, plug • Warranty: Not stated on this listing • Model: SMX920 • Rank: #17 in Power Hedge Trimmers (Amazon AU), #9,661 overall

Giantz 52cc Petrol Wheel Brush Cutter, 3 in 1 with Saw Blade
ASIN B0BC7Y26G7 • $149.50 • Sold by Artiss Furnishings on Amazon AU
The Giantz 52cc Wheel Brush Cutter is the one to push rather than carry, and at $150 it's the lowest-priced of the four picks. It's sold by Artiss Furnishings, an Australian marketplace storefront, and ranks #82 in String Trimmers, #27,088 overall. The listing gives a 52cc two-stroke engine, an easy recoil starting system and what it calls a well-balanced auxiliary rear wheel, and the title describes it as 3 in 1 with a cutting saw blade. Its manufacturer data states a 12-month warranty, one of two listings among the four picks that states one. Giantz isn't a brand we see often, so keep the order confirmation and the warranty details somewhere you'll find them.
The wheel is the reason to buy it. On flat ground, it carries the engine's weight so you guide the head along rather than holding it up, which is a lot easier on your arms and back over a big paddock, a long verge or a large lawn. The listing says it suits thin trunks, heavy grass and low grass, which matches what a wheeled cutter does best. At 52cc it's the smallest engine of the four picks, and that's plenty for grass and light scrub, though thicker woody regrowth will slow it down. The wheel also keeps the blade at a steady height, so the cut usually comes out more even than a hand-held cutter swung at different heights across a paddock.
The listing is thin: it doesn't state a power figure, the fuel mix, the weight or what the three cutting options are beyond the saw blade. It's less use on steep banks, in narrow beds or along fences, where you need to lift and tilt the head. Check the wheel for wobble before each job, since a loose wheel lets the blade dip into the dirt. Keep the wheel axle greased, check the blade nut each time and drain the fuel before winter. For flat, open ground where carrying a brushcutter all afternoon is the problem, it's the pick.
Honest caveats: The listing doesn't state a power figure, fuel mix, weight or what the 3 in 1 options are beyond the saw blade. The wheel makes it awkward on slopes, in garden beds and along fence lines. It's the smallest engine of the four picks.
Best for: Owners of flat paddocks and big lawns who would rather push a brush cutter than carry one.
Price: $150 (Artiss Furnishings) • Engine: 52cc two-stroke • Layout: Rear support wheel • Cutting: Saw blade, 3 in 1 per title • Starting: Easy recoil start stated • Warranty: 12 months stated • Seller: Artiss Furnishings (marketplace) • Rank: #82 in String Trimmers (Amazon AU), #27,088 overall

What we see fail in the workshop: petrol garden tools
Small petrol engines aren't what our workshop repairs, so this part comes from how two-stroke tools are built and from the phones and gadgets that come in after a day in the garden. Most petrol brushcutters don't die from wear. They die from fuel left in them, a filter nobody cleaned or an attachment that was never pushed fully home, and all three are faults an owner can prevent with ten minutes of care.
Varnished carburettors from stale fuel
The most common two-stroke fault by a long way is a carburettor blocked with varnish from fuel left in it over winter. The engine won't start, or it starts and dies as soon as the choke comes off. A clean and a diaphragm kit usually fixes it, but draining the tank or running it dry before storage stops it happening. Mix fresh fuel each month or so, label the can with the date, and swap the in-tank fuel filter every season. A primer bulb that's gone hard or cracked gets replaced at the same time.
Seized engines from the wrong fuel
Straight petrol in a two-stroke is the fault that's expensive to fix. Without oil in the fuel, the piston scores the cylinder within minutes and the engine seizes, and the repair usually costs close to a new machine. Keep the two-stroke can a different colour from the mower can, label both and never fill the brushcutter from a can you're not sure about. If an engine suddenly loses power and screams, stop it straight away and check the fuel before you pull the cord again, because running it on will finish it off.
Phones run over, dropped or soaked
The garden fault we do see is the phone. They get put down in the grass and hit by the blade or a flicked stone, they slide out of a back pocket while you swing the cutter, and they get soaked in sweat or caught by the sprinkler afterwards. A cracked screen is usually a straightforward repair, but water and sweat can take a while to show up on the board. Leave the phone on the back step while you work, or in a zipped pocket, and wipe it down when you come inside.
Decision tree: which one should you actually buy?
- Clearing long grass and scrub on a big block? → The Baumr-AG 65cc Brushcutter at $239 has bull-horn handles, anti-vibration and a stated 12-month Australian warranty.
- Want a brush cutter plus hedge and line attachments for the least money? → The MTM 62cc 7-In-1 at $189 comes with a pole hedge trimmer and line trimmer attachment on a quick-change coupling.
- Need a pole saw and hedge trimmer as well as a brushcutter? → The Baumr-AG SMX920 at $339 runs pole saw, hedge, line trimmer and brush cutter heads off one 65cc engine.
- Mostly flat paddock or big lawn, and carrying one is the problem? → The Giantz 52cc Wheel Brush Cutter at $150 rides on a rear wheel and states a 12-month warranty.
- Small suburban yard with neat edges? → A cordless trimmer is probably the better buy. Our cordless lawn mower guide covers the battery side.
- Phone met the blade, a stone or the sprinkler? → Bring it into our Erina workshop and we'll check the screen and the board and tell you the cost before you spend anything.
Frequently asked questions
What's the difference between a brushcutter and a whipper snipper?
A whipper snipper, or line trimmer, spins nylon line and is made for grass along edges, fences and garden beds. A brushcutter has a bigger engine and a stronger shaft and gearbox, so it can also run a metal blade for long grass, thick weeds and woody regrowth. Most brushcutters can run a line head too, which is why the names get used for the same machine. All four picks here are brushcutter class, from 52cc to 65cc.
What fuel does a two-stroke brushcutter use?
Fresh unleaded petrol mixed with two-stroke oil made for air-cooled engines, at the ratio in the manual. None of the four listings states the ratio, so check the manual before the first tank and mix in a marked fuel can. Never run a two-stroke on straight petrol, because without the oil it seizes within minutes. Most small-engine makers say to avoid ethanol blends above E10, and many say to avoid E10 altogether, so follow the manual for your machine.
Why won't my brushcutter start after winter?
Nine times out of ten it's stale fuel. Petrol left in the tank and carburettor over winter evaporates and leaves a varnish that blocks the tiny jets. Drain the old fuel, fit a new in-tank fuel filter, mix fresh fuel and try again. If it still won't run without the choke, the carburettor needs a clean and probably a new diaphragm kit. Next time, run it dry or drain the tank before it goes away, and it'll usually start in a few pulls.
Is a 4-stroke brushcutter better than a 2-stroke?
A four-stroke runs on straight petrol with oil in a separate sump, so there's no mixing, and it's usually quieter with a smoother idle. A two-stroke is lighter for the same power and simpler, with fewer parts to wear. None of the four picks is listed as four-stroke, because the four-stroke trimmer I found on Amazon AU came from a seller I couldn't confirm as an Australian retailer. Whichever you buy, choose one you can get serviced and warrantied locally.
Do I need a harness for a brushcutter?
For anything over about 40cc with bull-horn handles, a harness makes a big difference on a long job. It takes the engine's weight on your shoulders and hips so you swing the head with your body rather than holding it up with your arms. The Baumr-AG 65cc and the MTM 7-in-1 both have bull-horn handles, and neither listing says a harness is included, so check the box. The Giantz has a rear wheel, so it doesn't need one on flat ground.
Are multi tool attachments as good as separate tools?
For a home owner, mostly yes. A multi tool runs a brush cutter, line trimmer, hedge trimmer or pole saw off one engine, so there's one carburettor to look after and one fuel can to mix. The trade-off is the coupling, which needs to be kept clean and fully engaged or it wears and slips, and long attachments put a lot of weight at the far end. The Baumr-AG SMX920 and the MTM 7-in-1 are the two multi tools among the picks.

Phone met the blade or a flicked stone?
Phones put down in the grass get run over, hit by stones or soaked by the sprinkler, and sweat in a back pocket can take a while to show up as charging or speaker faults. Bring it into our Erina workshop, and we'll check whether it's just the glass or something underneath, and tell you what it needs and what it costs before you spend anything.
