6Pcs Lawn Mower Blade Sharpener, 5CM Universal Multi-Sharp Grinder Wheel Stone Rotary Lawnmower Sharpener with Blade Balancer for Most Power Drill Hand Drill (Blue)

Grindstone okay but plastic backplate wears too easy - replaced mine with 50mm metal washer.

Only tried using one out the pack. Didn't make an impression on blade but the actual stone stopped rotating

The reason it's not 5 stars for me is it does not fit a commercial blade as to thin and the thickness doesn't let it in. How ever if you had a normal lawnmower this would be ideal I use a commercial mower

The grinding wheel fell of the pin on first use

Excellently made product, doing its job!

Great Value for money really good item
