Re: first aid
You are talking to the first aid freak here,lol. I have certifications in CPR for the professional rescuer, Solo Wilderness First Responder, Lifeguard and first aid...A staple kit, although it might be useful in a really bad scenario, I think is probably a little overkill. I would suggest having putting in your kit various sizes of gauze pads, a few gauze rolls, something for applying pressure such as an ace wrap or cloth bandage. If you have a really bad wound anyway, you'll want to apply pressure to it, and stapling it, if you are out in the wilderness, you are more likely to probably get a nasty infection. Better to wrap it up and get to a hospital somewhere. Of course, hopefully that won't happen. Solo WFR was a course I took last summer, intense training of emergency care in the wilderness; didn't talk about staple kits. Just my two cents. If you want to know about the staple kit, then I'd suggest talking to a doctor or search google or something.
