Funny thing. The whole time I'm reading this thread I keep thinking, "I really dig all of Mike Vellekamp's designs. I wonder what it would take for him to to a collaboration with Spyderco."
Then it dawns on me, "oh yeah, that's right. He used to work for Spyderco. . . " So, maybe his influence has been felt in a lot of stuff that's come out in the recent past.
Even still, I really love love love the ergonomics and lines on his most recent kinves, and I can't help but wonder what some of them would look like with a Spyder-hole. But that's just me, and YMMV.
At any rate, Mikey and Sal, if you're reading this please know that you guys are both tops on my list of top-notch guys who make the kinfe community so exciting and fulfilling. Keep up the great work, wherever it may take each of you.
