My sisters and I took Kali for many years. It prepared my sisters before going away for college. Growing up I was always fascinated with all kinds of weapons. I started making my own, unfortunately, none of them are non-lethal.
ADDED:
I work in military installation and I am not supposed to bring firearms to work but this is what I have in my drawer at work.

A pocket knife for cutting fruits and meat, the bigger knife for cutting cakes (everybody in my squadron uses it). The sling shot is for the hallway shots. I also have throwing knives and flying picks (broadhead) but it is concealed in my locked drawer.
