Yosh- just to be clear you want to learn certain WC techniques that are deadly or learn to defend against a gun, knife, bat ect..???
as far as deadly like "dim mak" style things i have no idea like joint locks pressure points?
as for the latter, if you want to learn to defend against a knife, what we do is get some washable markers and white t shirts, a dot is a stab wound, slash is well a cut obviously, grab a couple markers and go at it
for a club like a bat we use a whiffle ball bat, it stings but not too bad
