While he doesn't know it yet, my son (10) has a Evogrip S18 coming his way for his eleventh birthday in August. He inherited my love for SAK's. I wanted the Evogrip, as it has a perfect grip (duh), but more important, the blade locks.
He already has Classic SD (red) as does my daughter (8).
I have a Color Twins (green) in the mail as I type this. I'm very anxious to see it irl. Plus, I have set of vegetable knifes (pink) for the misses in the mailbox.
