Love my sharpener ... I got it at Joann's ... nothing fancy it' s a circle with sandpaper. Directions are clear and easy to follow. It has extended the life of my blades, which I but in the five pack on sale of course. I also bring a friend to go shopping with that way I can buy 2 things on sale. I buy blades from Harbor Freight as well because they are cheaper. You get 2 blades for about $1.50. Sometimes there are nicks, sometimes the sharpener smooths it out and if not I just bring it back to harbor Frieght. Hope this helps
