【NEW】Double Layer Corundum Lawn Mower Blade Sharpener, Universal Wear Lawnmower Blade Sharpener for Any Power Drill/Hand Drill, Double-Layer Grindstones Easy to Use and Not Easy Damage-(Gray)

This is product works great and easy to use.

This corundum blade sharpener does what it claims – it CAN sharpen lawn mower blades, and it’s easy to use with any standard power drill you likely already have at home. As an added bonus, I was even able to use it to touch up some of my kitchen knives, which was a nice surprise.That said, there are a couple of drawbacks worth noting. The sharpening stones tend to wobble when spinning at high speed. I suspect that’s why so many reviewers mention theirs breaking on first use – the instability puts stress on the stone. Because of that wobble, I couldn’t insert the mower blade between the two grinding surfaces as intended. Instead, I had to hold the blade perpendicular to the stone and sharpen one edge at a time. Not ideal, but it still worked.Fortunately, the set comes with three sharpeners, so if one breaks (which is a real possibility), you’ll have backups ready to go.Overall, it's a functional tool for the price – just be careful during use and manage your expectations. For occasional sharpening jobs, this set does the trick.

Great design. One of the best and easiest ways to sharpen a mower blade at the proper angle. There are other options, but they are far more complicated and/or convoluted. Attach this to your drill, clamp down your blade, and sharpen away. Very quick way to get your mower back into service. Fits your standard power drills.

I get it. They want to sell three, to raise the purchase price. You get three cheap gizmos beveled equally on both sides. If your lawn mower blade is flat on one side and beveled on the other, you'll need to do a LOT of grinding to eventually get it sharp. Alas, the cheaply-made gizmo won't last that long. Mine broke clean in two on the second use. Oh well, I have two more cheap gizmos left. Suggestion: sell three different kinds: equal bevel, beveled on outer edge, beveled on inner edge.

I honestly had such high hopes with this product though the excitement was quickly shattered as the very first bit I put on my dewalt drill role as soon as I turned the drill on never even touching it to a blade, I changed the bit thinking things happen maybe it was just 1 bad one out of the 3 but I was wrong I put the other one on and soon as I touched it to the mower blade it quickly shattered in half the stone actually broke in half so I put the last and final sharpening bit on my drill and barely touched it to the blade and was able to sharpen one side of one blade before it separated and broke as well. Poor quality and poorly built doesn’t even start to describe this product. I will be returning this product as it was a waste of $10 do not buy this product it will break before you get to use it sorry but just facts

Sharpened as expected. It takes some angling and patience, but you can get a sharp blade. I have used a file for years and as with everything new it will take a few sharpening sessions to get it down pat.

I have tried it have a problem with the Thick blade won’t fit maybe it’s me I’ll try again

I was honestly shocked at how easy to use and effective this sharpening pack was. I used it before mowing my lawn tonight. Tilted the 42" zero turn back, using a 4x4 about 3' tall to hold it up at the deck, and sharpened the blades without taking them off. They were as dull as the handle end of a butter knife before and after about 30 seconds on each end of the two blades (4 in total) they were as sharp as a bitcher knife. The dual edge (groove) of this product helped significantly with keeping the grinder on the blade. I used my Ryobi brushless to run the tool and imagine any driver with medium to high power would be effective. I wasn't expecting much based on some of the poor reviews but I was pleasantly surprised. It was a 5 minute job and the blade mulched like it was new again.
