Most griffons, warriors at least, tended to wear bladed gauntlets on their foreclaws which accentuated their lethality, designed more for swiping and slashing than grappling. It was much like Shortbeak had done before. That said, you did not want them at your throat—they did not have to be all that lethal in their own right to end your life when they were that close to something suitably vulnerable and soft.
