I get what all the fuss is about now

Yesterday I received my Signature FK3 (first new CPK) and when it came out of the package, I actually said, "Wow!". It appears to be very high quality and feels great in the hand too. I buy a lot of knives and can be hard to impress. Mr. Carothers managed to do just that.

After squaring up the spine and putting a convex edge on it, it's just what I've been looking for. The factory edge was very, very sharp, but I've been playing around with convex lately.

I get it now and will get to work building my CPK collection immediately! Sorry. Got excited for a minute.

Do you have pics of the modified edge? I'm curious to see it.

I'm going camping tomorrow and will try to get a few pictures (au naturel) for you Patrick. I plan to build a kindling fire with the FK3 to start my charcoal after batonning some kindling with this beast of a knife. I'm such a nerd.

I'm not sure how to post pictures yet, but I'll give it a try.

Congratulations G GimmeCPKorGimmeDeath on scoring an FK3 as you first CPK. It is a great all around choice for most outdoor uses.

Two thoughts come to mind from your post:

1) On your next CPK, I suggest that you spend some time using it with the original factory edge to compare with your convex modification on the FK3. Nathan optimizes every feature of his knives including edge geometry for cutting performance. Some comparison testing will help you better understand why he sharpens the way he does.

2) Be careful to avoid using any power equipment on your CPK blade(s) if you choose modify them because the heat generated will ruin the temper of the blade.

Welcome aboard the CPK owners group. Have fun and be safe.

It is easier to overheat the very apex of the edge than people realize

It doesn't take a whole lot of heat to relax the matrix around structures that are pinning slip planes at a nanoscopic scale, and your Delta 3V will then be just 3V
 
I appreciate the info everyone. I should clarify that the convexing was done with diamond stones only. No power tools. :) I kept the 20 degree angle and cut the shoulder down a little bit at 17 degrees, then used lapping films to round it all out. If I had to guess, the cutting edge is probably around 21 degrees now.
