Well shucks, Frank... I believe this might be the first time anyone has begged to differ with me on these here fora
I'll bite that the Leek is not a straight Wharnie... but I have to say that among the knives in front of me at the moment, it's definitely the straightest profile of the lot.
I've got a Mini Grip with that Sheepsfoot thing, a Kershaw Scallion, the Bugout of course and the very piece that is in your photo there... the CF Leek.
While not completely straight in the edge department, it's the straightest that I've got. And while I love it to death, I tend to use the more "bellied" examples more.
The CF Leek is one I'll never let loose. The steel is one of my favorites, the CF is beautifully done, and I do like me a good liner lock. It's a fantastic EDC to be sure.
I'm still solidly in the "Both" camp.
