This impresses with its ease of use, thanks to which it can be used to create a new cutting bevel without any problems. The various clamping elements are used to clamp knives with different blade back thicknesses. The perforated plate is used to be able to clamp knives with wider blades without them protruding too far, which could cause them to start chipping. For sharpening, the universal knife sharpener is placed in front of a belt grinder with the knife clamped and the desired angle is set using the adjusting screw. It is then pushed until the blade almost touches the grinding belt. Now you can move the blade to the left and right thanks to the ball roller guide and slowly press the universal blade sander against the belt.
