A Ninja

may intentionally throw a knife so that it lands
flat or strikes a target with the butt of the handle, in an
attempt to subdue or stun an opponent. This is a difficult
technique to master, but it can be used to capture enemies
alive or simply to render them unconscious. Such stunning
blows are usually to the head.
Special Uses
Ninja may attach small blinding dust bombs, smoke,
explosive, or incendiary grenades to throwing knives in
order to increase their effectivenss of lethality. A simple
flaming knife, used to start fires, can be made by wrapping
strips of cloth soaked in flammable liquid around either the
handle or the blade (depending upon how the knife will be
thrown). The strips are ignited just prior to throwing the
knife.
Poisoned knives are another special use. Even a nick or a
scratch from a poisoned throwing knife can prove fatal.
Poisoned throwing knives can be made by coating the blade
with poison paste. It is best to throw poisoned throwing
knives by the handle. Avoid coming in direct contact with
the poison.
