Abstract:
1. A universal sharpening jig for a cutting blade comprising: a base plate; a protractor plate coupled to the base plate; an incline plate hingedly coupled to the base plate and slideably connected to the protractor plate, the incline plate configured to secure the cutting blade and configured to set and fix the angle of the incline plate with respect to the base plate to define a sharpening angle of all or a portion of a bevel with respect to a flat back of the cutting blade; a push plate slideably attached proximate a front of the base plate and co-planar with a bottom surface of the base plate, the push plate configured to position a user-applied force vector thereon and directly apply the force vector closely proximate the intersection of the bevel and an abrasive surface to reduce de-stabilizing moments and user energy need to create a sharpened edge between the bevel and the flat back of the cutting blade; and at least one glide located proximate back of the base plate configured to longitudinally and/or laterally level the base plate with respect to a level abrasive surface to allow movement of the jig in all horizontal directions by a user to create the sharpened edge on the cutting blade.
