It appears to be a model 10 ground differently than a Crider. Note that it is not quite a spear point like the Crider, and the bottom bevel is pure model 10. If you look below the logo and name etching, the grind kind of rises and raises the mid line from where it would be on a Crider or a standard 10 grind, resulting in the top bevel being shallower than the bottom bevel.

It appears Bo took a model 10 and tweaked it for someone he knew.

Then again, what do I know?
