Thanks Roger for the History lesson and doing the Sunday Picture Show.
The Buck Honemaster is a jig that assists in maintaining a consistent angle when sharpening. The angle is determined the placement of said jig and is somewhat limited as to the range of angles possible. It has a pivot (hinge) and a single screw so there is no adjustment for parallelicity, cannot hold skinny blades very tightly (because it holds only with the lips of the jaws), and the size precludes the use on small blades. See photos 1 & 2.
Jigs of this type are set so that distance between the tip of the blade and the corner of the jig is equal to the distance between the edge of the jig and edge of the blade. See photo 3.
The knife is drawn, edge leading, across the stone, and the handle is lifted at the end of the stroke to keep the blade on the stone while tip gets sharpened. See photos 4 & 5.
Count and match the number of strokes on each side to keep the edge centered.
Raise a burr on each side of the coarsest stone to insure that the grinding planes go all the way to the apex.
Polish the tapers on successively finer stones to get the desired degree of sharpness. Be sure to wipe the swarf off the blade and jig to avoid contaminating finer stones with coarser grit. Butchers stop at about 400 grit and align the micro teeth with a steel. Their slicing is often done with a sawing motion.
If you want to push cut, go on up to 4000 grit.
Since Silicon Carbide and Aluminum Oxide cannot abrade Vanadium Carbide, use Diamond or Cubic Boron Nitride to sharpen blades with that inclusion.
The Honemaster would work on longer and thicker blades.

thank you Sir for taking the pics of the setup and the explanation of how it works. appreciated.
 
Not one comment, huh. Do I just have a plain silly sense of humor?
