How would you protect yourself? At home, on the street, or in a vehicle what would you choose and why? I carry a large tanto style locking folder. Durable, sharp and easy to open with one hand. In my Jeep I have a sharpened Cold Steel special forces shovel. Good tool, will slash like a sword or chop like a hatchet and looks like a shovel not a weapon. Next to nightstand I have a Wakizashi style short samurai sword. Shorter blade easier to wield in a room. Still enough to strike at a distance and slash, stab or chop up a burglar etc.
