just a thought

- i dread to think of the legalities of this.
Ugh! i've tripped a 9mm version of these and thats enough, i've heard the 12gauge blanks go off from accross an airsoft site!
you'd certainly scare off just about everything within 200 yards!
as for knife verses staff, well my old Aikido sensei used to say something about confrontation. See it was during a day of extremely excruciating knife disarm/attack stuff when he said.
"Simply put if someone comes at you with a knife, what do you do?"
after some discussion over technique the correct answer turned out to be:
"Run"
i think thats pretty common sense and it makes you realise how dangerous knives can be in the wrong hands. if a 5th dan Aikido Sensei would rather Run from a knife then use his years and years of training, confidence and technique to disarm Uke then simple put i would not want to try it either!
As for staffs, i'm a BIG fan, first of all they *look* intimidating, second they can be wielded with either precision or with force which make them fantastic HTH weapons. Alot of people seem to believe that a staff should be used like a club, or held in two hands and spar with it like 'Little John' in all the robin hood clones.
Amazing how much trouble you can cause with a simple jab or thrust from a staff, how much leverage you can apply to a body in motion and how much you can just throw people about without them realising that they can in fact fly for a few seconds.
plus they're great for keeping you upright, pitching a basha, testing wading depth and attracting funny looks from people as you walk down the highstreet
