20 Best Grit For Sharpening Lawn Mower Blades (2022 Updated)

Best blade sharpner I have used to date. I was doing blades for neighbors and found out what a bad job they did with keeping angle if cut. This sharpner is perfect. Don’t hesitate pulling the trigger.

It will pay for its self in no time.

Very easy to set up and use. Does an excellent job of sharpening blades. This is a well built tool, and it has a quality appearance. There is nothing cheap about it. Its expensive, but after using it, I would say this is one time you actually get what you pay for.

A little on the expensive side. Doesnt clearly show what degree you are sharpening at . Other than that its great

I have one of these Smith’s Sharpeners and its works well. Doing one or two sharpenings yourself will pay for this device. And if you have a vise to hold the blade still , it makes sharpening so much easier.

It does take 10-20 pulls across each end of a dull blade , to get it sharpened enough. I like mine really sharp because I cut 2 foot tall pasture grass with my zero turn mower. This is a sturdy tool and wont damage a blade like a power grinder will.

Blade wore down after just a few uses. Plastic holding blades scraped down. Replacement blades only $3. 75 but postage is $5. 95. Not worth it. Good for a few passes – 4 or 5 sharpenings but after that it is useless.

When I got the sharpener my blade was so dull I used it immediately and it worked just fine. You really need to keep your mower blade sharp or else it’s going to tear the grass and it doesn’t give you a good smooth cut.

So this is an easy way to keep the correct angle on the blade and to get the edge sharp again.

Product is incomplete. Handle does not function as it appears, one has to tighten the bolts down on the blade to keep it in place. Blade grind angle was also very shallow. I have drilled it out and added a bolt to tighten arbors together and adjusted the blade grind to a perfect 30 degrees.

Also modified a 5/16 bold to use on my grinder. Basic design of the unit is sound and very heavy made. If you don’t mind a little tinkering you can make a very nice unit out of the machine for little more that a piece of 3/8s all thread and a couple nuts.

I would suggest negotiating the price.

It was everything the video and ad claimed. Mounted it easily the edge and angle were spot on. This was strictly for personal use since I cut 11 acres weekly with Grasshopper zero turn. Finish cut looks great.

You could not tighten down the blade To be able to sharpen it you would have to be able to tighten down the blade This product does not work it is junk

The thing works well but I think it is way over priced for what you get. If I had the time I would build one . It would not be hard to make one.

I have had other diamond stones in this size (3″ x 8″) that were not nearly so good (they pealed off surface pieces over time). This has worked well for quite a long time. I get a good edge from the 1200 side.

I haven’t used the coarse side. Recommended.

I was surprised when I received this blade, expecting more from Oregon. One of the cutting edges was poorly ground with gouges in it. So much so that the blade had to be filed back to restore an edge.

The other edge was passable but was very roughly ground (at least no gouges). I spent an hour with a hand file and brought the edges up to snuff, making sure the blade remained balanced. It was mounted on a Toro 60V Recycler.

This blade is heavier than the Toro factory blade and affected how the mower handled (the personal pace became somewhat grabby, possibly from the inertia of the heavier blade), and did not show any improvement in the mulching ability.

After sharpening, the blade did cut well (good clean cuts on the blades of grass), but so does the OEM blade. I changed back to the OEM blade after giving it a touch-up, and I can say that I prefer its performance.

The mower handled better, and I believe the lighter weight of the Toro blade will be better regarding the life of the mower also. I’ll be buying Toro brand recycler blades from here on out. My lawn is 2500 sq feet, a mixture of Kentucky bluegrass and rye, and gets mowed in the spring about every 3-4 days.

This blade is not made to fit a john Deere 54″ mower. Not even close! Don’t waste your money. Buy a different blade that is actually by the manfracturer for this mower. Tried everything including filing it down with the grinding wheel and then re-balancing, even that did not work.

And you surely can’t return a blade once it has been modified to hopefully fit the mower you purchased it for. This blade was not cheap so it was an expensive lesson learned. Go to the John Deere dealership and buy the one that they recommend.

Do not waste your time or money on an what is supposedly a better after market product. Stick with the manufacturer’s brand, it is less expensive and less fustrating in the long run plus you will be mowing your lawn a lot sooner.

I have a 22 HP Simplicity Lawn Mower with a 44 inch mowing deck. I have always used a bagger with high lift blades. I have redone my entire lawn with hydro-seed and wanted to try mulching to build up the soil and conserve water.

I removed the bagger and mower deck shields off the mower and installed the G3 Gator blades. I have now mowed the new lawn 4 times with the Gator blades. Using only the side discharge on the mower deck the Gators do an outstanding job cutting the grass with less strain on the mower.

However want to mow your grass towards evening when the grass is completely dry in order to avoid any clumps left on the lawn after mowing. I live near Seattle and will use the Gator blades until late September then switch back to the bagger and high lift blades in order to pick up the pine needles before winter.

Very pleased with the Gator blades and the lawn looks great.

Oregon 28841Sharpening stones for a Dremel. These are no better than China knock offs they most likely are China. Maybe Sharpened one Chain before they broke and fell apart. If not falling apart they just wear down really super fast not even applying that much pressure.

I do not recommend these.

I have used the Oregon brand in the past with excellent results. From this set there were 2 that appeared to be either brittle or not assembled correctly. While doing a normal sharpening routine, the grinding stone cracked and came loose on the shaft.

Another one just broke off the shaft. I was not using excessive pressure, just letting the stone do the work, and the faults happened.

They are very expensive and lately tjey been falling apart during use. I used to sharpen 10 or more times before changing the last time i didn’t even get one sharpening out of a stone.

I really like the design of the stone with the finger grove on the perimeter. It provides for good control of the stone when sharpening and a good safety aspect. I like the dual grit and the fine side puts a nice finished edge on my axe’s.

Great product!!.

I had abused my axe for a number of years. The stone brought it back and possibly better than it’s original factory edge. The stone was easily to use and effective. The size of the stone was easy to work with.

don’t get rid of you’re reel sharpen it and adjust it correctly and will have healthest best lawn of neighborhood and it will easier to use, no gas, no oil, no noise. you will never go back to a blade mower again.

why do you think golf courses use them.

the instructions were not exactly right. i had to use a wrench to get the screw off. then, there is a little pawl you are not supposed to let fall out. it fell out 100 times. i could not get the crank handle on over the pawl.

i may have gotten a faulty handle. i even tried to hammer it on and it never got all the way on the reel shaft. i managed to sharpen the blades with the handle not on all the way. im not sure how sharp i got the blades yet.

i wouldnt call this a nightmare, but it was not fun. i will have to do it again and i am not looking forward at all. i am female and this may have something to do with it. not sure.

Excellent! It brought a neglected 20 year old 16 inch reel mower back to life. Now the mower works great! Cut almost an acre of grass and the lawn looks beautiful. Highly recommend it if you need to sharpen your reel mower.

The sharpener arrived quickly and is as discribed. Easy to use and my lawn looked great after having a nice newly sharpened blade to mow it with. I did have to take about 50 strokes on each side to get it sharpe enough but my blade was very dull.

The blade sharpener was delivered in one day, fantastic service!! I used it immediately and was completely satisfied and aware that it would save me money on blade replacement due to not grinding away too much material.

It made me feel like I was a machinist and knew what I was doing. Wow !! wish I had one of these twenty years ago. Thank you, George Radeackar.

I need to recieve it first i have 8 pair of blades waiting on its arrival!!! On Mon, May 10, 2021, 11:03 AM iGoPro Lawn Supply wrote: If this email is not displaying correctly, please click here to fill out the form.

Works as advertised! It gets the job done without the guessing and you see the results of the work. Just got it. I feel like I should just sharpens blades to make money instead of cutting grass!!!

Having received this item promptly I put it in my drill and set about sharpening a lawnmower blade. Within a very short time it broke (started spinning in the spindle so no pressure could be applied).

A couple of washers later sorted it out. However the stone wore out before I could finish the blade. Really poor product. The price reflects the quality Im afraid. Spend more and get a better one.

After years of not sharpening my lawnmower blade. They were very blunt. This definitely made them sharper. Reading the comments about it breaking, I didnt put too much pressure on the stone, just added a little bit of oil while grinding.

Not the best out there but cheap, very cheap. I sharpen two blades before the thing brake so still cheaper than professional sharpening. Just don’t expect it will last forever. Blades ware sharpened properly though.

My partner is fussy about sharp blades, pruners and knives. He’ll stop what he’s doing and sharpen my tools anytime I ask, but I prefer to just whip out the drill and sharpen them myself whenever possible.

I keep this in my garden tote and pop on a cordless drill and I’m good to go! works for me.

Bought this sharpening tool for my lawn mower blade. It was all good at first but after applying some pressure, the screw is just spinning and the grinder head doesn’t.

The plastic guide that keeps the blade in place doesn’t stay where it is meant to and didn’t even sharpen one blade before becoming useless. Waste of money. The guide and shaft need to be machined from one piece of metal.

Dremel has provided me this product in exchange for an honest review. I had no trouble using the attachment to sharpen a chain saw blade after reading the directions multiple times and watching a 3rd party YouTube video.

Anyone new to sharpening might not know what “blade pitch” is and would be totally lost using this product since using the incorrect grinding stone would be easy to do, resulting in a ruined blade. A video from Dremel showing proper use and selection of the proper grinding stone would be helpful.

Additionally, the directions for a new user are difficult to follow so they must be read several times before attempting to sharpen anything. The attachments for lawnmower blades and lawn tools worked fine though I found myself off angle several times because of the width of the attachments.

An adjustment device of some sort to keep the grinding stones firmly against the tool would be beneficial.

The Dremel A679-02 sharping kit is exactly what I needed. With one kit I have everything I need to sharpen my chain saw, clippers, and lawn mower blade. Im especially excited to be able to sharpen my chain saw.

I use my saw just enough each year to dull the chain and then make poor cuts for a couple of months before I break down and buy a new chain. Now I can quickly and easily sharpen my chain in just a short time.

I can easily see this chain lasting 3-4 years now. If I only get one extra season out of the chain by using the Dremel kit to sharpen it the kit has more than paid for itself. Dremel has provided me this product in exchange for an honest review.

The ” Dremel A679-03 Rotary Tool Sharpening Kit” is a nice small kit that I have used with my Dremel Rotary Tool. I did have a couple issues with the coupling getting a bit loose but working on that part.

I actually used this tool to sharpen my Lawn Mower Blades. I have a Honda Twin Mower and this was perfect size and power. I did not have to take the blades off this time like other sharpeners. This made it easy to sharpen on the mower and get a clean result.

Smaller enough to get right into the corners of the blades with no kickback!! Great attachment.

Firstly this was quite difficult to fit in the right position, but after a while I managed it. However, the screw fittings are made of cheap plastic and one of them broke when I attempted to push the mower as instructed, and the sharpener fell off.

I tried using it by placing the mower on its side instead, and turning the wheels by hand, but this did not seem to have any effect on the sharpness of the blades. In the end I used one of those cheap hand-held knife sharpeners which cost about 2, sharpening each blade of the cylinder by hand.

This worked reasonably well and seems to have improved the cutting capability. Overall I am disappointed with this product, it is cheaply made (metal fittings would be better and would not cost much more) and it does not work particularly well, and is very expensive for what it is , ie, a bit of plastic and metal with some sandpaper stuck on it.

I suspect this high price is charged because people see it as a cheaper alternative to professional sharpening (I was quoted 30, which is half the cost of the mower itself). But if you want to save money I would suggest using one of those cheap knife-sharpeners first.

Don’t over tighten the attachment screws as they are just plastic. Just enough to hold the bar securely. Don’t try to take too much off in one pass. Adjust the blade gradually. I took about 30 mins to get to a decent sharpness with an even cut across the width.

Simple idea, easy to use & perfect results. Follow the easy to understand instructions & the blade is as good as new. Used on my 30 year old Qualcast 30S Punch & saved paying 55 for a regrind. Only used one abrasive too.

I have just used this wheel with my HSS wood turning chisels. It removed the material faster than the originally supplied wheel. I am very happy with it.

I use this when I need to remove more metal to repair or re-shape blades. It is harder than the standard stone and allows me to then use the standard stone for final sharpening.

i bought this to replace my old stone with had a set spot this mush better than the original stone that i have

After reading the reviews, I ordered this. I am not disappointed, but still have a few wishes. As mentioned in reviews, I wish it had the adjustment turn handle. Instead, it has a little wrench which will probably get lost.

Also, after using it, the 1/2 hp motor also got very hot. I was hoping the 1/2 hp wouldn’t do that. I am a bit worried about that as far as life of the motor. Overall, glad I have it as it provides a quick turn around on my blades.

Sharp blades are mandatory when mowing. I change mine, and sharpen them, almost every 8 hours of mowing. For a healthy lawn, you should never use a dull blade.

This works perfectly. Follow the directions to set up at 30 degree angle but dont learn how to from You-Tube. Keep table secure and use it as a guide, and dont lift blade like on videos. It just ruins the edges.

Blade grinder works well. I’m just opening up a lawnmower shop, and this will pay for itself. Saves time and money. I also ordered the dust collector and mulching blade adapter. Machine works well. Was concerned about it not having enough power, but it has plenty.

Doesn’t even bog down any.

Worked perfect. Learned Technique by watching video. Perfect pack. I placed mine in a cloth bag and fits perfect in back pack. Light on weight. I use mine with a little water poured over it then start course side then fine tune it with smooth.

Seems good for field knives, hatchets,axes, murals and machete, as it does the job but is not a pretty area where the stone touches. My axe had hit a few rocks in the past so I was pretty aggressive.

I prefer finer stones but did not take a star away because the item was as advertised and appears well made. This is very course one side and medium course the other. If the edge has chip/s, a file is quicker for removal.

If you don’t have a suitable file, this would work. Again, well made, just not for my style of sharpening.

I was wanting a sharpening stone to tune up my machetes I purchased this (puck) thinking I wouldn’t need a fine grit but a course to medium. Well went to work on my good machete after putting in a couple hours work with it,wow was I suprised after all my agonizing attempts at getting a machete blade sharp I had finaly found the golden egg.

I’ve tried grinders last attempt files stones diamond,but this pick is what it took to get the correct angle and grit to that steal and start it back on the road to sharp sometimes to sharp for a machete.

I pulled out my cheap machete same story couldn’t hardly believe it. I’m very happy with my purchase. !.

I purchased my mower used, and knew it needed to be adjusted and or sharpened. I adjusted the reel and bar to the correct friction setting, and the paper test proved it needed at minimum a backlapping.

I ordered the kit, and it shipped the next day. It arrived in 3 days, and I was eager to use it. I viewed the online video so I was familiar what was involved, and what to expect. The instructions included with the product were clear and matched what was shown in the video.

It took me a total of 10 minutes to backlap the reel to a super sharp, and uniform across the knife be. I now have a clean paper cut along the entire bar. Prior to sharpening, the paper would bend on the outer reel ends, and would not touch the paper towards the middle.

I could hear metal hitting metal, but the reel leading edge was not honed or flat, and appeared worn and rounded I used a square head lag bolt that had a 1/2 head and inserted the head into the sprocket tool that was included with the product.

I put the lag screw side into my 3/8 variable speed battery drill that is reversible. No need to buy a step down attachment for the attachment. Super happy bringing my abused used reel mower to a super new condition.

What was more a tearing cut or pinch and lift action because of a dull blade, now is super sharp. I have enough compound to do 20 more sharpenings! My bermuda putting green is in excellent playing condition, and will be for years to come.

I bought this product as my new California Trimmer would not pass the paper test. My lawn looked uneven. I admit I had a little problem following the instructions. However, with a little patience, I was able to figure it out.

Within ten minutes, I was able to complete the backslapping. Now, my lawn looks little le the back nine at Augusta. (Perhaps a slight exaggeration).

High quality and very easy to use. What a difference in the cut of my lawn after using this kit to backslap the reel and cutter bar. You save a lot of $$ by not taking it to a shop to perform this work which can be done easily at home.
