【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)

Worked great on mower blades! I would buy again.

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.

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.

not much differance than using an off the shelf grind pad

Not for first time users.I am not happy with this product.The directions and videos fail at teaching people new to this process.I am not saying the product is bad, I am saying it should say use by more experience users.I recommend removing the blade from the mower, the videos all show the process being completed while on the mower.

I used this to sharpen my lawn mower blades and it worked great. My grass stems were cut nice and evenly. Very pleased with this sharpener.
