I've always had a cat mind, so I'm very attracted to the tiger style martial arts, but I don't have a teacher anywhere near me, as I'm living in the middle of Montana. So I'd like to know what other martial arts outside of kung fu have clawing techniques as a central or frequent point of the martial art.
First, within Kung Fu styles, you may want to look into Eagle Claw Kung Fu or anything with a strong chin-na techniques as part of their curriculum.
In penjak silat, there is a variety of harimau (tiger) styles, with the Sumatran styles going quite low to the ground, and matjan styles of standing tiger. Many of these use a small curved knife known as the karambit for attacking and controlling.
I've also seen a bit of East Indian fighting arts using palm claws primarily as a wrestling/disarming tool (as much as shredding the thumb muscles or fingers 'disarms' a person).
