ABSTRACT:
A blade holder, for use when sharpening and honing a blade, to hold the blade at a fixed angle to the abrasive surface, comprises a frame, one or more rollers and clamp. The frame has a front plate, against the inside surface of which is clamped the front face of the blade. Since the blade's sharp edge is between its front face and its relatively narrow underneath face, (which extends obliquely to the thickness of the blade), the location of the blade's front face by the frame's front plate enables location of the sharp edge irrespective of whether the blade has parallel faces and irrespective of how thick the blade is. The roller is mounted on a shaft at the back of the frame. One or more clamping screws extend transversely of the shaft axis through one or more screw-threaded holes in the shaft to engage a clamping wedge member which is slidably guided in the frame for clamping the blade to the front plate of the frame.
