This jig is used to hold a swivel knife at the appropriate angle while it’s blade is being sharpened. The one hand piece can be made to hold any of the common swivel knife barrel sizes simply by placing the appropriate sized bushing into the hand piece. The bushings come in four sizes and are made to hold any corresponding sized swivel knife using two nylon tipped set screws.
Hand pieces and bushings are machined from aircraft grade aluminum and anodized. These tools are made in the USA, and a patent is being applied for.
