I just went ahead and bit the bullet on a plain edge, tanto Griptilian. I would have liked to get the "normal" blade shape (not the sheep's foot), but everywhere had them out of stock or overpriced.
I almost bought him a Ritter RSK MK1, but then I realized, I might have ordered that for him, but secretly for myself. Can't have that, can we? It's his birthday pressie.
He likes to modify things, so at least with the Grip, he can buy a set of Wilkins to replace the standard grips.
Plus, 126 shipped was out of my budget at the time (price of the RSK MK1).
