Unarmed vs. Knife

[mlangsdorf]

I'd also got with Toptomcat's answer, with a slight change: Retreating puts you farther from the knifeman, and makes it hard to close into his hex to effect the arm lock. It's generally better to Sideslip and then step into the foe's hex for the grab.

After the arm lock, a throw from the lock will generally break the knife wielder's arm, effectively disarming him, if the lock wasn't sufficient.
