The blade sharpener is surprisingly a small piece than I had expected. I was easily able to load it to my power drill. The sharpening part was very simple and easy to use. I am pleased with the results.
They work great. Makes putting a clean sharp edge on the blade so easy.
Bought to sharpen my lawnmower blade. I've never sharpened a blade before, it took about 7 minutes per side of the 12" blade. I would to hate have done that by hand!
