I've been looking into the Kershaw Spec Bump, but I don't know what to think... It looks really nice... the handles look great, it's cool looking, I like re-curved blades (that one's a little much but that's minor)... it really looks to me like it ALMOST belongs in the ZT line, but not quite. The only problem is the lock. I've never even seen a thumb stud lock (i guess that's what you call it; correct me if wrong) until I came across this and I'm not sure what to think. Any thoughts about it???
