My PSK is not strictly a survival kit per se, it is also a "wilderness utility kit". I totally agree with your original post, and if survival is your only goal, you can go with a lot less items in favor of bleeding first aid, etc.

However, my kit has zip-ties, a small pencil and paper, some duct tape, paracord... sometimes the line between a pure "PSK" and a PSK-utility kit hybrid is difficult to draw. But what I wanted in my kit in the first place, were some utility items and things for those situations where you go "gee... I wish I had a bit of ______ handy".
