Buy me a bench grinder and I'll use it Otherwise I'll stick with my angle grinder thank youbrNot everyone can afford or has access to special tools Comment from : Jonathan Charczenko

Lmao 😂😂😂😂 this is the most ridiculous video I have ever seen on YouTube I’ve been working on mowers for 55 years and sharpening blades with an angle grinder every single time This video is made for people who don’t know how to even pick up an angle grinder and obviously by someone who doesn’t use one very often Comment from : Liberty Forever

Apparently, you don’t live in Vermont where rocks pop up every year from frost heaves I am careful mowing, but hitting them is inevitable and I have to sharpen my blades several times per year A flapper disc on the grinder is the way to go and sometimes even that takes quite a while Balancing always follows sharpening Comment from : Low and slow

I guess if you still live at home with mommy and daddy you have time to do this! Busy people have to do it the "quick" way! 😂 Comment from : G Bo

you haven't convinced me to do it any different what are you going to say next , were not shoveling our driveway properly Comment from : old fart

The file is the correct way to sharpen But you are filing the wrong way You file down towards the edge Opposite way you are doing it! Comment from : Tom Gulley

Like a die grinder this method is OK for a straight blade but totally useless for a contoured blade Please show me an easy substitute for an angle grinder when sharpening a contoured blade Also, a bit of a contradiction You say the angle grinder will remove too much material, but with a really dull blade, to maintain the correct angle it will usually require the removal of much metal Comment from : UtwoBed

Some good tips Thanks Comment from : Ian Mclean

You're discussing the "correct way" to sharpen a blade of any kind while holding a hand file? Get a grip, Pumpkin So you think you can put a 45-degree angle on a mower blade with a file? If so you learned in the biClose Enough is Good Enough Acadamy/i/b Get a bSorby Pro Edge Plus/b and stop guessing Better yet stop showing people how you do something half-assed and babbling about it being acceptable for those that didn't attend your academy Pumpkin Comment from : Brian Bassett

Yes It does Removes too much of the blade Causes the blade to be off balance That is common sense Comment from : james walters

More importantly whatever you use The main key is to not let the metal turn colors That means it's too hot and will distemper the metal Comment from : matt marshall

Sure if you dont know how to use a grinder or how to sharpen blades Comment from : matt marshall

I want to see you try that with a top tier commercial blade thats 1/4 thick and almost 3/8 wide grinddI wont mention the carbon level of a good blade either Like filing a diamond Comment from : TrollHD PC

I use an angle grinder all the time No issues whatsoever Comment from : GJ MULLER

OK, well, you missed an important part What do you do if your blade is out of balance? How do you correct? Comment from : livenhfree

Use a 30 or 60 grit flapper disc and it will not remove too much material Comment from : Ricky Ius

I buy new blades every other year I find new blades are not sharp to begin with I find it’s a waste of time to sharpen them and yes I have the tools needed! Comment from : shop Art

Agree with the other folks who use an angle grinder A flap wheel is the way to go since they grind the metal without taking too much at a time I do agree that free-handing it can be an issue (except for those who are much more skilled than I am), I recently purchased the All-American Blade Sharpener (actually a blade vice) that you attach your angle grinder to and set the angle Holds the blade tight and you get an a precise angle cut Using a nail or one of those cycincal balancers makes sure the blade is balance Comment from : Bill Cuningham

It's $20 for a new blade Comment from : Red Dingo

Bench grinder Very lightly just until you get a "shine" That'll work Comment from : Jerry Woods

You take off more material with a file honestly man you done know anything Comment from : rogestep

For a home cook, the best investment I made Comment from : Raymond Salazar

I was sharpening blades while he was weining That grinder WONT kill your blades Comment from : Jim Dodge

I mow for a city by the train tracks I wish my blades ever even looked half as good as the used ones you are sharpening Comment from : Shaun Spriggs

After watching this whole video, I'll keep using my angle grinder Comment from : Crocs on lets go!

So how do you fix an imbalance blade, replace it? I guess so because you didn’t give an answer for that Comment from : Robert Dillon

You'd have to be very low IQ to destroy your blade with the most efficient method, which is using a flap disc and grinder Comment from : Ten-pound-nipples (yes,just my nipples weigh 10 £)

Quality blades at fair price Comment from : 똠양꿍

Lightweight is good and what did I use it for it’s a lawnmower wwwyoutubecom/post/UgkxTPN04aT-Qdjr_KS3ql7ng8wnU3wwsCqk also recommend Yes it is lightweight so hence not as robust as our old one But if you take care it does the job really well Comment from : Rhonda Burrell

Worth the price Comment from : Andy Jame

A Dremel tool with a tungsten carbide spiral rounded bit sharpens a blade without even taking it off Tip the mower on its side like you are going to change the oil, get the correct angle, take your time going in one direction After sharpening, just one little pass to remove any burrs on the non-angle side and its done Comment from : Capt Ken Baker

Rubbish Comment from : Norman Brooks

If you care that much about a perfect blade just buy a new one for less than $20 Comment from : Special T

I agree about keeping the mower blades sharp! But, I have been using an angle grinder for years If you go lightly, it works perfectly and makes quick work Comment from : John Steed

My 2011 troy bilt riding mower was vibrating itself apart including 2 broken motor mount bolts I replaced the blades before a 3rd bolt broke and everything is fine now running smooth like a new mower Comment from : Gary65437

Flapper disc has worked 4 me 50 yrsits called skill corncobT800Aust Comment from : Gavin Elliot

Bu😊y a new blade Comment from : Lucas Romero

Hmm I prefer to work my way thru 17 diamond laps, from 100 to 10,000 grit I find that after a week of careful polishing it really leaves a pristine finish on the grassbrbrJk flap disk all day, well not all day, like 60 seconds Comment from : Chris

File works great Comment from : Bobby

what a jackass Comment from : dustbustr91

Maintenance only in the fall ? Really ? Comment from : Alex Hall

Your file had two different sides which is good You didn't mention that the side you used first was a double cut file which has crosscut groove lines on it This is the type of file you want to use to sharpen a mower blade Double cut file, they take off more metal quicker to make sharpening faster and easier I don't even need a vice Just hold down blade , like on top of garbage can and file away Skim file the bottom edge too, and the finish edge is razor sharp Comment from : John Reuille

I mowed grass in the late 80's I was a farmer before I took on mowing grass for the public On the farm we would take plow points Subsoiler points, and shanks, and use a hard surface welding rod to weld over the parts of the shank, points, that wore So I did the same to my lawn mower blades Even put a bead on the cutting edge They stay sharp longer Some companies sell a hard surface blade now But they do not put a bead on the cutting edge of the blade, or wear it wears the most Comment from : Charles Coker

An angle grinder can ruin a blade if not used carefully Anytime you’re running an angle grinder and you see the steel turning black or blue you’re grinding to much too fast and it’s ruining the steel Many people don’t hold one steady enough to keep a consistent 30 degree angle on the blade The last time I paid a lawn mower shop to sharpen my blades they came back with all kinds of angles and blued spots on them from overheating A professional lawnmower shop that’s too cheap to buy a dedicated blade sharpening machine should quit Comment from : Prevost

I prefer an old bastard (file) 😂 Comment from : ciara respect

iGNORANT VIDEO TRYING TO SELL CRAP Comment from : LowLife

My blades are almost as dull as the handle of a butter knife when I sharpen them I'd literally have to spend hours on a set of 3 blades if I used a file AND would still have to balance when finished I may get about a year out of a set of blades before the fin that creates vacuum is worn so thin that it may start coming apart Take your time and you can achieve the same results with an angle grinder and still do it in a fraction of the time And yes, balance it as best as you can Bearings will appreciate that! Comment from : scburdett

Jesus Christ 3 minutes just to get to the point Comment from : Chris Beber

Using a file does not guarantee a 30 degree angle will be held, nor does using an angle grinder guarantee excessive material loss A file can be more forgiving, as it takes longer to get in trouble I have done A LOT of metal-work I am qualified to use a file OR an angle grinder to sharpen bladesWhen I'm earning a living I use a grinder When I'm amusing myself,having fun, I use a file or two Comment from : CHARLLESS

The blade is not destroyed That is the wrong information The blade gets dull quickly is more like it The science behind it is when the metal gets hot, red hot, the dang metal grains is distributed, that is why they quench to align all the grains again (when the grain is aligned the metal is harder and stronger than when they are not) The trick is running a stream of water over it so the blade doesn't get hot while the metal is removed Not only that the sharpening is quicker, but you can remove a lot of metal such as the new axe with the wrong profile of the "ground" Knife making process are the same, but they quench after grinding for the same reason (of course heating up in the oven first to the right temp before quenching) Some lawn mower blades are really hard to sharpen with a file, the hardness is way up there Comment from : Reel500

My wife bought me a lawn mower sharpening tool to hold the grinder at the proper angle with the proper grinding attachment Now I have mallet finger because she wanted me to sharpen a blade that didn't need sharpening and pinched my finger between the guard bar on the discharge and the tip of the blade Comment from : jacksonmich jackson michigan

as a machinist that created blades for my neighbor I agree with this video if you need advice on grinding metallic iron for f16 fighter jets fuel transfer parts I'm the guy Comment from : Ip Man

works for me I use it a lot abd i know how to edge it Comment from : Israel Ortega

I use a silicon knife sharpening stone my mower blades are sharper than my butcher knives in my kitchen and it's quiet Comment from : Dylan Desmond

How did you remove the blade? Comment from : thomas fair

I agree that a file works well on a blade that is barely dull, but in reality, most people let blades get very dull A flap disc works very very well in this situation A file would take awhile and wear you out For those who don't know how to balance a blade, simply grind/sand/file a little more off the heavy side until it's balanced Comment from : Mark H

ALSO GUY,USE THE PROPER DISK,LOL YA JUST NEED SOME COMMON SENCE,LOL,IF YA NOT A MECHANICALLY MINDED DONT DO IT,LOL Comment from : Henry Franz

Mower bearings are not affected by the blade being out of balance Each blade has a belt going to it Maybe the bearing to each blade might be affected though Ive always use a hand grinder Key is to watch how the grinder touches the blade Just touch the blade and always round off the ends of the blade at the same angle Thats where the most cutting takes placeon the end of the blade ! Comment from : jerry lansbury

I just used files todayand no problem Doesn't really take that much more timeand I don't have an angle grinder so Comment from : Jsweizston

If you are still using a file I'm sorry Let some one interduce you to a flap disk and make another video Comment from : Eric Kirklin

Good video! Comment from : Robert Simon

That is a new blade that you sharpen dude Comment from : Gamer Family

I would not listen to this guy because he sharpen a brand new blade My blades never looks that new Comment from : Gamer Family

I use a file You have total control over material removal Comment from : Quisp

If you sharpen blades for a living you can get pretty good with an angle grinder at maintaining the correct angles Wall mounted blade balancers are a great tool to really be sure it's balanced so you can be sure you don't have vibration when fitted back on the mower What I see a lot of people doing is sharpening another angle to the under side of the blade which should be kept flat, this is bad don't do it for two reasons, the blade will dull quicker and also it's the flat under side that keeps both ends parallel to each other for the most accurate cut If the bottom is rounded off you need to grind the angle all the way back till it's flat again, this is often the case with blades and can take a lot of grinding Comment from : steven holmes

FYI The sharpening starts at 4:40 Comment from : Jim Lcher

HUH ! I'll have to try a cutoff disc instead of the grinding wheel on my angle next time The backsides of my blades are missing or shredded , but maybe that's because I put on a smaller deck belt ? Comment from : Airon Noles

Use a 120? Grit sandpaper wheel, works awesome! Or a manly file! Comment from : Dad

Definitely not the way to do this Use a flap disk on a angle grinder Comment from : John Bialek

If you aren't stupid, angle grinders work well Comment from : Brian Adams

I concur a hand file is the way to go, it will do a superior job and you will be done before you can find your angle grinder Comment from : Stuart Seible

I also use a file i think it is a better edge and if you sharpen your blades as often as you should, it is easy The only time i use a grinder is when i have let the blades get to dull or dinged Great information here Comment from : Ray Bechtel

Te quedo perfectamente Comment from : Herman merloss

So how do you balance the blade if needed? Comment from : Mike Smith

A flap disc works good Comment from : Phil

You would have to file for an hour to get that blade out of balance Comment from : Mike O

Angle grinders a good way to go I get a beautiful job every time and you don't need a flapper disc Comment from : T R

My old boss would have kicked you in the nuts for back dragging a file Comment from : Willie Pelzer

Don't quit your day job Comment from : Willie Pelzer

Hence an Angle Grinder, guytf Comment from : Shaft

Bitch, I'm not balancing my mower blades I'll buy a new mower when it breaks lol Comment from : D P

BS, my 40 year old Snapper has it’s blade sharpened every year with my 45 inch angle grinderbrStill cuts perfectly! Comment from : Robert Verhasselt

Agree 100 I use a mill bastard file with a handle Duck soup to sharpen a blade Takes off minimal material and only check balance once in five sharpenings Comment from : Inquisitive

I see a mistake you are making with the file, you always sharpen into the blade not away Just like when you sharpen a knife Comment from : Ted Reed

Sorry dude I can quickly and easily sharpen the mower blade with an angle grinder, and unless you have a vision disability; it is quite easy to maintain the 'angle' of the original edge no different than trying to keep your file at the correct angle super fast and effective PLUS, if YOU slip, you are likely to cut a major arterythat isn't going to happen with the grasping areas of an angle grinder Comment from : Todd Gill

basic engineering , learn how to use a trusty file, when I served my apprenticeship over 60 years ago no one had an angle grinder! these were just basic skills you learnedand they work for you all through life Comment from : Ron Valente

of its not balanced do you give it a few wacks of a hammer? Comment from : Damo 007

Great tip! Comment from : visar idrizaj

Lol Comment from : Okie Dokie Push Mowing

I run through 6 sets of blades a week this would take a week to do Comment from : Garrett May
