Winston
> 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?

FWIW, here's the drill buffing kit I used, in case others want to try it out. At $10, it's worth a try.

I found that initially, I didn't have the wheel centered very well on the arbor, and so the amount of pressure on the chisel varies a lot as it spins. I got it more centered by shifting the wheel around and pulling the drill's trigger, and repeating until it looked better. I think that this may be why my initial attempts didn't seem as sharp as a chisel right off the 12000 grit stone -- the off-center wheel resulted in more pressure, which resulted in more rounding. With this most recent attempt, I was able to apply a more consistent, light pressure. (I may have also held the blade at an angle closer to tangent to the wheel, but I didn't pay much attention to angle for the first few chisels, so I don't know for sure.)

> 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?

Do you mean that the rounded portion is larger or smaller than what you expected?

I based the scale off of the hair that I measured to be just over .002" with a micrometer. I think it's pretty accurate, but I can check on it again. There is a bit of growing and shrinking of the image as the camera tries to focus, but it's not huge. Maybe a 20% difference in size from largest to smallest.

> 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.

I suspect that you'll still need a fine stone to work the back of a chisel on occasion. And there's still the matter of plane blades...

> The other audience is looking for durability. Is this 0.001"edge durable? Probably yes is it looks like Weaver's.

I'll try to do a durability test at some point.
