i'm going with a good fixed blade knife myself. self-defense weapon, duct tape it to a stick to hunt with, butcher meat. you can even shave with one if you know how to sharpen it...ask Jethro on NCIS about knives...
My vintage drill, so old I can't even remember who I inherited it from.
...... and if anyone wants to hear a really fabulous true story about how I used this drill to smoke out two well-know, elderly spiritual Masters from India, just let me know!!!
