I would find my opponent spontaneously bleeding to be the exact opposite of intimidating.

Thats why I said it rarely works. Though, some people (by some i mean most) in the real world, are actually VERRY thrown off by the sight of blood. It more often than not will affect someone mentally, greater than physically touchig them would. Some gamers, and most soldiers seem imune to this effect. Other people may be, but the lilelyhood is slim. Generaly, blood throws people off.
