A grinding jig for holding a blade tool having an edge in a grinding machine. The grinding jig may have a first and a second clamp half arranged to hold between them at least a portion of a blade tool. An elongate support portion may support the grinding jig onto a support bar of a grinding machine. The elongate support portion may comprise a front end abutment surface and a rear end abutment surface. The front and rear end abutment surfaces may be spaced to receive a portion of a support bar such that the grinding jig may be moved back and forth relative to the support bar in a direction parallel with its longitudinal center axis.

The present disclosure is directed to systems, compositions, and methods for manufacturing objects with sharp edges having a high strength and hardness. To form the sharp edge, an object can be subjected to a compressive force that locally deforms the object to create the sharp edge. In some embodiments, deformation can occur by passing the material through a system of one or more opposed tapered rolls having one or more tapering angles for deforming the material. The tapered rolls can rotate and drive the material downstream to a next opposed pair of tapered rolls. The tapered rolls deform the material by changing the material microstructure, compressing the grains of the material in a predetermined location to create a more homogeneous microstructure. The local modification of the resulting microstructure increases the homogeneity as well as the hardness and strength of the material and prevents cracking and/or chipping of the material.

A tool sharpener has first and second guide surfaces to respectively support a cutting tool adjacent first and second abrasive surfaces. A drive assembly moves the first and second abrasive surfaces with respect to the first and second guide surfaces. A control circuit directs a user to place the cutting tool against the first abrasive surface using the first guide surface to sharpen a cutting edge of the tool during a first sharpening operation. The control circuit activates an indicator mechanism at a conclusion of the first sharpening operation to direct the user to perform a second sharpening operation in which the user presents the cutting tool against the second abrasive surface using the second guide surface to sharpen the cutting edge.
