Knife Sharpening Machine

Knife Sharpening Machine

Knife sharpening machine. Homemade knife sharpening machine, working on live traction and implemented on the basis of a bicycle. The thing is certainly very useful, especially for places where access to electricity is difficult for one reason or another. The truth is to work and simultaneously twist the pedals is not particularly convenient, but in time, probably, you can get used to.
