Original Design knife-handling clamp. This extruded aluminum knife handling clamp can hold almost any blade. The notched jaws provide secure and exact blade handling on almost all blades, including most narrow blades (such as tiny swiss army-type blades) 1/2" wide and under. The spare knife clamp is intended for use with the American-made Lansky Controlled-Angle System: the easiest, most effective way for you to get the consistent angle you need for a professional edge on all your sporting, shop and household knives. Dozens of system accessories are available such as specialized hones for serrated blades.
