With this original Tormek knife jig you can sharpen most types of knives. The jaws of the clamp adjust to suit different thicknesses of blade. Restore the blade to its original edge angle or choose the angle you prefer. The jig rests freely onto the Universal Support so you can follow the curve of the blade and get an even bevel. The edge angle can be fine tuned by turning the handle. Use SVM-45 for ordinary and smaller knives down to a minimum of 70mm blade length.
