What martial arts are based around daggers/knifes?

[DanielArismendis]

Im a big fan of short blade weapons and i always wanted to know how to fight with one

 

[aaronr]

look up any Filipino art such as kali escrima or arnis( they are all closely related) and are first and foremost blade arts

go to ninja academy or samurai school for that
