I keep a Sjambok in a handy location on my recumbent bicycle. Very few people would even notice it, even though it is in plain sight. I love cold steel products! I have a few years of Filipino martial arts experience and I love playing with sticks & knives. I had no problem when I broke one of several Cold Steel throwing knives I own, they replaced it ASAP.

My usual choice for a sock knife when kilted in non-formal situations is my Jaguar M4 Balisong.
