The Knife One of the most useful tools invented by man. The knife is probably the most commonly carried weapons on the streets today. More available than guns and more accepted than any other weapon. Of course most people don't know how to use a knife and they can be a danger to themselves as well as to others.
Knives vary dramatically.
From the small pen knife or switchblade to the machete, from straight bladed stiletto to the curving blades of the bich'hwa bagh nakh tiger claw weapons of the Middle East and India. From single bladed knives to double edged serrated and barbed blades. The list of variations in styles is astonishing. This fact alone makes the ubiquitous knife a deadly weapon. If you are ever attacked with a weapon, you have a very good chance that it is going to be a knife.
