Negative relief 116 Uniform-Parallel graver template.
This template is the same as the normal 116°, but the relief grind under the heel is negative. The purpose of this negative grind is to achieve more heel clearance. This additional relief was described in the Lindsay Uniform-Parallel patent, but this is the first template made available to actually achieve this point.
This template requires that the height of the grinding lap or bench stone be 3/4" instead of the usual 1/2" seen in all previous templates. I recommend just shimming your 1/2" stones up the last 1/4". The plastic 6"x6" plate included with the full sharpening kit happens to be 1/4", so that can utilized.
A power hone for initially shaping this is helpful. However it can be done with the diamond bench stones. Steve tested how long it would take him to sharpen one from a carbalt blank on the diamond bench stones. It was 15 minutes. Of course starting with a the 3 degree tapered carbalt blank would considerably shorten the time. | Negative Relief Universal Template
