This is the finest and easiest jig to use for the precise and consistent sharpening and honing of hand plane blades. Hand plane blades have a slight camber on either side of their edge. Using a straight edge jig can help create this camber but it takes time and relies on eye judgement. With this jig, your blade is automatically positioned at centre of the jig and the blade is rocked to create the camber. The angle at which the jig can rock is adjustable by rotating two adjustment knobs on the underside of the jig. The jig can hold any blade up to 70mm in width. ©
