【2020 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)

I’ve used this double-layer corundum blade sharpener for three lawn mower blade touch-ups over the past month. As someone who’s sharpened blades manually and with bench grinders, I found this tool surprisingly efficient. It attaches easily to a standard drill and restores a clean edge in minutes. For routine maintenance, this sharpener is a time-saver and well worth the price. Great for homeowners who want to keep blades sharp without investing in bulky equipment. Four stars.

Liked the design and easy to use . Quality is good but not great . Size is as shown.

Klappt 👍

Schlechtes Material, bei erster Benutzung in mehrere Teile zerfallen.

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.
