The Kuba-Shiv by Thompson Knife and Tool is a unique cutting tool that comes in a nice pen-sized package. Here is what the maker had to say about it: "It's a fixed blade made for every day carry, has a removable tritium vial in the handle. 6.5'' O.A.L. and weighs less than 2oz! Glass breaker end cap with lanyard hole. Material is Heat Treated 440c. It can be pocket carried, neck carried, purse carried or belt carried in a vertical or horizontal position. It looks like a pen when worn in the pocket, very unaggressive looking until it comes out. It is a very capable knife with a small footprint. I designed this model with the saying ''a knife in the pocket is better than a machete at home'' and ''nobody reaches for a knife they don't have''. This is a knife that can be carried comfortably all the time." Knife is in excellent condition and comes in kydex pocket sheath.
