Knives!

This page is devoted to one of the oldest of weapons and a great tool - the knife!

You really don't have to have much money to get a decent self-defense oriented edged weapon. Please don't carry around a worthy knife designed for fighting. Nearly all of them are illegal, depending on your locale. The way of Budo includes preserving many martial arts. Some are relatively ancient. Others are almost a millennium in age or much older. Some are very modern (Gendai). Just like knives, these many martial arts come in many shapes and forms. It's up to you to learn about the differences in them. I suggest that all forms of the martial arts have value in one way or another.
