Sharpens blades quickly

Sharpens well, easy to use. Saves to buy a new blade. Using a vise to hold the blades is preferable.

Good for sharpening mower blades

I was able to sharpen my blades. I liked the balancer so I could determine if I removed to much metal from one side of the blade. You will need a drill to use this product.

Works well, especially for the price. This is my second one. First one lasted several years.
