Everyone should carry a first aid kit when out and about. The problem I have had with "kits" is they supply bandages for scrapes and minor cuts. I figure if I need a bandaid I don't really have a problem. If I need a bandage the 4 inch square gauze bandage is not going to get the job done. It's easy to see how you could plunge a knife into your leg while cutting up an animal or stick yourself with an arrow. Or worse yet one of your friends.
I came across this revelvation after shooting my first animal with a bow and arrow. I thought what would happen if I cut myself similarly. Big problem. So to remedy this I when to the drug store and purchased the biggest bandage that would fit into my day bag. ( 12x16 ) square. This is a thick bandage similar to a battle dressing you might find in an Army/ Navy store. It is always in the bag and takes up little space.
Matches, heat tab, water, food and shelter won't help if all the red stuff is gone.
