One way to distinguish different kinds of martial arts weapons is by using the two-group system, edged (bladed) and blunt weapons (nonbladed). If the weapon doesn’t have a cutting edge for slicing or a sharpened point for puncturing, chances are it’s a blunt weapon.
Blunt weapons cause damage by bludgeoning, clubbing or stunning.
The father of all weapons is the staff (aka guin, quarterstaff, pole, cudgel, bo and stick). Every culture has developed some version of the staff, and it’s one of the four basic martial arts weapons. As such, it’s spawned many other weapons.
Common martial arts blunt weapons that aren’t practice replica weapons of edged weapons include the bench, Buddha hand, club (nunchaku, three-sectional staff, truncheon), crutch (tonfa, cane), fan, gold coin spade, hammer, hard nine-section whip and iron ring.
