This is a huge pet peeve of mine also. I cannot comprehend why there are so many "knife designers" out there that cannot just make a handle that feels good and works! Makes me want to become a knife designer! I could do so much better than most of what is on the market. I think that most knife designers, and most high end knife buyers, never really use their knives, so they would not know the difference anyway.
Especially what peeves me are these "tactical folders" that have horrible handle shapes. There are tons of them out there, with no type of guard, little or no index grooves, nothing to keep your fingers from slipping up the blade, and no form fit to your hand. What is so "Tactical" about pulling out a knife when you are in dire need, and slipping on the handle and gashing your self open...only adding to the dire need you were already in.
No thanks. When I shop for a knife, I look at the handle first. Most people get hung up on the blade. I can make any blade work, but the handle has to fit. Heck, I can make a well designed box cutter wdo most jobs. Any length or style of blade will do. The handles on many modern box cutters are far superior in shape to the handles on many high end folders. Go to Home Depot and check out the box cutter selections, some of them really feel great in the hand.
That is why I keep going back to my AFCK. The handle is very well designed (thanks, Mark McWillis, if you are out there). And, I can get it in M2. Sure, I would prefer an Axis lock on it (attn Benchmade: when are you going to get on the ball and make the knife we have all been begging for for at least a year now - An M2 AFCK with an Axis lock!).
Other winners in the regard are the Emerson Commander and the KFF, but I still end up going back to my trusty AFCK.
I consider "blade presentation" part of the handle also. I like a knife that curves forward so the blade edge addresses my target easily without torquing my wrist to get it there. The AFCK wins there as well.
If I wanted a dagger or an icepick, I would look for something else, but when I want a knife to cut with, I want the blade to naturally address the target in a cutting motion. The AFCK is an outstanding design. So far, my liner lock has not failed on mine, even when I hammered it through a car hood, but I would still like to see an Axis lock on an AFCK.
