Bests & Worsts Reviews from Amazon

I'm very surprised by how well this product works. I make knives and sharpen my knives by Japanese wet stone or belt grinder. I sharpen my mom's and grandma's knives by stone whenever I visit. I've tried to teach my mom to use a honing stick while I'm gone to keep the knives in good shape, but she can't seem to get the hang of it, so I decided to buy this product because of the simplicity of use. I tested it on a few of my dull knives at home, and it takes about 10 strokes on the course grind, and 10 strokes on the fine grind to get a sharp enough edge to slice printer paper without tearing. I love how simple and how little time it takes to sharpen a knife enough for kitchen use. I can get a knife much sharper by using a stone or belt grinder, but for normal kitchen use, being able to cut a piece of printer paper cleanly is good enough. Now my mom and grandma can sharpen their knives whenever they need it. I highly recommend this product!
