Received my Kershaw Zing and am very happy with it so far. I've had Kershaw knives in the past, and like the assisted opening a lot. This one was SUPER sharp out of the box, too. I am curious if the thumb stud can be removed easily. I never use it, and it's just something to snag on. I wouldn't mind a small hold in that spot if the stud just screws in/out.
