I'm currently a freshman in college. 19. I've had a wave since elementary school. This thing has held up great. Even with all the improper ways a kid who doesn't know anything about knives used it.
I suggest the leatherman super tool. The charge and the wave can easily pinch you fingers if they slip off a nut. Leatherman's warntee is very good. I have sent several knives back to be sharpened got new knives back.
