are offensive techniques used to immobilize your opponent without causing him
or seriously risking of causing him any bodily damage. Pins are rarely, if ever,
used in self-defense as they require significant technical mastery as well as
physical strength and, even more important, can’t be used in fight against
pins are serving the same function as joint locks
as both used to control and limit movement of the opponent. The difference is
that while joint locks primarily using threat of pain as means of control, pins
limiting movement without causing pain.
this doesn’t mean that pins have no practical applications, but just that those
applications are not in self-defense. General Schwarzkopf
in Vietnam to save
his wounded soldier on a mine field, first responders and controllers in
psychiatric institutions use it to subdue delusional unresponsive patients (who
may be in pain or in aggressive shock), correctional officers may use it to
subdue prisoners in some situations, etc.
