I hate to be that guy, but I feel that it should be said. Firstly, let me be clear; this is entirely MY opinion, and YMMV. As such, the blade is great and as with every Spydie, it carries their trademark all around excellence in build quality. That being said, I have some complaints about the design. Call it... constructive criticism. And really, this is the very first time I have ever had a complaint about a Spyderco. Anyway, first off, the handle and scales are thin. Too thin. I realize this was a design choice to cut down on size and weight, but it is uncomfortable in my hands because of this, and I have medium/average type hands. It cuts into my hands because I feel like I have to white knuckle it to get a decent grip on it. Secondly and lastly, where the hell is the jimping? There is none on the rear of the finger hole and none on the thumb ramp. Seems like this is obvious? I feel a bit disappointed in it, as I did drop near 200 bucks on it, but I also realize this is the first iteration of the blade, and it is basically a prototype, if you will. I am going to keep the knife, and get some thick custom scales for it, as I do like it, but again, I feel a bit let down.
EDIT: And I forgot to note that I prefer the blade on a karambit to have more curve to it, and the Karahawk as is, is more of a Hawkbill blade on a karambit body.
