Hand Tools
Bill Tindall, E.Tn.
The Unicorn Profile has what seem to be three attributes, two closely related- fast and sharp, and, durable. the question in the minds of the bystanders is what does it take to get these benefits? The variables are buffing compound, wheel type, wheel speed, angle the tool is presented, buffing time....others?
The shape of Winston's Unicorn Profile is what I expected it to be. At what appears to be 0.001" , the size was not. Winston, are you certain of your scale?
These results from Winston are going to be useful for those looking for a quick reliable way to get sharp. Hollow grind, seconds on a fixed or loose diamond plate, buff , done. Cheap, quick, easy to master. It would seem that this procedure just obsoleted expensive stones.
The other audience is looking for durability. Is this 0.001"edge durable? Probably yes is it looks like Weaver's.
David has demonstrated the durability of his profile. He achieves it with a much coarser abrasive gold vs white, 5 vs <1 micron by one source. To get durable is a longer profile required? Does David's procedure deliver a longer profile or different shape? Is the nature of this procedure such that the resulting profile does not strongly depend on most of the variables?
I think it would answer these questions best if David sent Winston something with his profile buffed on it to be photographed as a comparison. A comparison of white vs gold in one person's hands would also be helpful.
