Cold Steel makes some exceptional knives. I especially like their San Mai III blades (as in the above Black Bear Classic) and I own a Magnum Tanto II, San Mai III, (pictured below) that I bought when it first came out on the market about two decades ago. Blades of proper length and structure can reach vital organs even through heavy clothing and soft body armor. These knives are fine performers and a good buy compared to custom knives; however, they are not cheap and already represent a third to half the cost of a personal defense firearm.
