A tip for chamfering the spidey hole.

Have you successfully done this to your Spydercos? Pics of the mod would be sweet.

Any do's and don'ts to advise?
 
I actually like the slightly sharpish edge on the Spidey hole. It gives a little bit extra for my thumb to catch on when wearing work gloves.

I just did it on my gayle bradley with great results. I found the sandpaper method to be unsatisfactory, sanded parts other than the very edge. Simply press into the hole, give a couple of twists and done.

I don't mind having some bite to the edge, but it was removing calluses that I worked hard to get.

Never thought of that as a solution. I have a few similar in the basement.

I don't think i would run out and buy one just for this purpose, but I'm betting a good number of the members here have something similar laying around.
 
A simple swipe with some 400 grit sandpaper would also work. I'd advise going very slowly, many people have rned a Spyderco trying to smooth out a minor edge.

This x1000. Sand paper would work so much better I'd imagine. You want it to be really gradual.
 
I recall someone suggesting sandpaper and a marble or ball bearing of appropriate size.

This post is a result of messing up the finish of an expensive knife using sandpaper. This method contacts the sharp edge and nothing else.

I'm dead positive the hole on my PM2 is a lot bigger than .45", and wouldn't be at all surprised if my GB is bigger too.

Just broke out the dial calipers.
The O.D. of the chamfering tool where the blades stop is .62" the hole on my GB is .535". It worked great.

Cool. My PM2 feels perfect, but my GB is razor sharp, even for my calloused hands, to the point that it has kept it out of my pocket.
 
If I've ever had a very sharp Spydie hole edge I have used a corner of a Sharpmaker rod. About 3-4 twists should do it. I've heard of a lot of people wrecking knives by rounding the hole corners off too much. The hole edge is necessary to grip your thumb so go real slow.

I'm surprised that it worked- the GB is hardened tool steel, just like the tool itself is, and I wouldn't have been surprised if the GB blade was harder than the tool.

spyderco.com says that the hole in the military is 14mm. I couldn't find info. on the PM2 but I thought it was similar sized. 14mm= 0.551".

I was concerned about that too, with as hard as M4 tends to be.
