Medical supplies are an essential part of survival and planning can really save you some headaches. You cannot have too much gauze nor too many Band-Aids. Seriously, if you have the room then keep buying them. Sterile gauze is worth having a small amount of, and non-sterile a much larger amount of. band-Aids of all shapes are recommended, I really like the Nextcare tattoo type because they stick so well and help with blister protection as well as all sorts of small cuts. I am not really a big band-Aid person as I like blood and scars, but to each his own. If you feel the need to stop bleeding, nothing beats good old fashioned pressure.  There is an old saying in medicine:  "all bleeding stops eventually"s.  I guess it is supposed to be partly humorous but also is meant to calm those that tend to freak out dramatically at the site of blood.  Pressure on wound for a good two minutes stops the majority of bleeding wounds from knives, sharp edges, and puncturing.  Holding pressure directly is the best way to approach bleeding, then after it slows or stops, then wrapping it with a nice tight bandage with gauze between will stop 95% of non-horrific injuries.
