We’ve seen multi-tools before, but how about a multi-tool that happens to be in the form of a pen? The Smith & Wesson Tactical Survival Pen not only writes like a normal ink pen, but it can break glass and start fires. It’s made of Aircraft Aluminum with a screw off top that exposes a fire striker. You can even replace the cap with a smaller ringed cap, to convert the pen into a keychain sized writing instrument. The Smith & Wesson Tactical Survival Pen is available in several colors and costs less than $29 at Amazon.
