As in indirect way of bragging about meeting Gail Glesser, I was recently able to ask her about the lack of chamfer to the opening hole in Spyderco knives displayed at the Sturgis Rally. She pointed out that the presence of a chamfer had caused some users to miss the opening motion of the knife, when the knife was sorely needed. She explained that the "sharper" edge left, sans chamfer, enhanced the ability to draw and open the Spyderco knife. After playing with before and after samples, I had to agree with her.

As I carry Spyderco knives because my life does depend on it, the distinction was important enough that I will carry the latest version, lacking that chamfer to the opening hole.

Thanks again Gail.

My new Endura is not chamfered, and I like it better than my other models that have the chamfer.
 
I understand the reasoning, but my experience doesn't agree. I don't really care - it works well either way. As long as the hole has enough of a slight chamfer to avoid cracks forming on the sharp edge during heat treatment, I'm happy.

I have been using an Aluminum Oxide 3/4 inch Grinding ball at very low speed to place a chamfer on the outside of the hole. This grinds a concave chamfer about 1mm wide around the edge of the hole adding to the gripping traction of the hole edge. I think its the round shape that works better than the cone shape for increasing the traction.

The tool I've been using is #16708 Vermont American 3/4" Aluminum Oxide. I purchased it from Lowes Lumber store. It fits into my 3/8" chuck reostat drill.
