One of my ritual knives as a vampyre was a hand-ironed Indonesian kris that I carried on a belt in front of my pelvic region.
However, for defense, one of my favorite knives is the katar dagger.
A people with a similar name are the Katkari. They are one of the few collectives (tribes) that still eat rodents. Their name means Tiger Slayers and they have an interesting saying:
“We put our hands in the mouth of the tiger, open the jaws, and count its teeth. We are the Katkari.”
