Spyderco doesn't chamfer the opening holes anymore?

It takes me a while for me to notice things, anyway I have a good number of older spydercos and there is a distinct chamfer of the interior of the opening hole. They are all real comfy.

On all the newer spyderco's I have gotten in the past year or so, the opening hole is deburred, and there is a slight chamfer, but not like the comfy old chamfers.

I like the old way, I suppose I can get a patch of emery cloth and work on it myself a little.
 
Hi Dave. We found that the large chamfer didn't work as well as the small one. A large chamfer creates a ramp that permits the finger to slip out of the hole too easily, especially if there is a strong detent to overcome in opening or the finger is wet.

I can attest to what Sal is saying. If you play with some of the Benchmades that have holes, they are severly chamfered. Your thumb can slip out of the hole much easier.

There's a balance to strike between a comfortable hole and a functional one. Too rounded and there's no traction. Too sharp and you can actually cut your thumb!

Calyth, a chamfered hole is one with rounded edges.
 
hm.. ok... funny, my Commerative Worker isn't very rounded either.
 
Folks,

I also noticed awhile ago that a couple of my older Spyderco knives had a severe chamfer of the opening hole compared to the new ones, and these I find downright slippery compared to the newer (less chamfered) ones. The older style looks somewhat nicer, but for me is not nearly so functional and in one case (an old style Delica w/ FRN clip) the hole is really quite "slick"!

I heartily approve of this change.

I have had several new spydies over the last couple of months and the non-chamfered hole makes it much easier to open the knife without slipping.

I too have an "old lefthanded AFCK which is really chamfered but it opens sooo smooth that it does not matter.
 
OK, I can understand the change, I would agree that there is less slip with the new hole profile.
