Knuckle Blade

Knuckle Blade
Crit: 20
Type: slashing
Size: tiny
Cost: 3

This weapon allows the user to deal lethal slashing damage with his
unarmed attack while still keeping the same damage he would normally do.

Feats and abilities can be applied to this weapon whether they are
originally for Knuckle Blades or unarmed attacks, but they don't stack if taken for both.
While fighting using a knuckle blade, the character does not benefit from critical range or
bonus increase that applies only to unarmed attacks. This does not affect techniques
with the kick descriptor.
