This works great for sharpening my knifes and makes it easy to flip over the mount for the knife. I gave it 3 stars because the threaded part is a little bent, I am guessing from a little force on it. When I screw it in it feels like it will break off. I will continue to use it until it happens. I mounted this to a piece of wood for better base stabilization.
