The knife is the "great
equalizer." An opponent with a knife can defeat
you, no matter what level your skill. This is the
"knife wielder's edge." Once a knife is present,
anything can happen.
In attitude, it is transparent. It reflects and
magnifies the personality of the wielder, rather than
changes it. It can be forceful in the hands of the
thrust-and-kill attacker, or subtle and tentative in the
hands of one who prefers to hit and run.
There are some who are adept at throwing the
knife. Others shudder to think one would be
thrown. My practice is to use a fighting knife for
fighting, and a throwing knife for throwing. In
essence, they are two different weapons. Regardless of
what you're holding, throwing should be done only when
the hit is certain.
Responding to your feedback, I am including a video clip
which provides some insight into defensive knife flow,
including use of hands and position as elements of
strategy. This clip is, excerpted from our
instructional video Sticks,
Tricks and Useful Bits,
which is no longer in print. You can find the
entire video online at Youtube
Remember, knife is a
complete martial art in its own right. All this
clip represents is a glimpse into fundamental concepts.
