The main purpose of surgical kits & sutures in a medical kit is to impress people who don't know any better. Except for perhaps removing splinters or lancing a blister, they are almost useless. Yes, I know the conventional wisdom about leaving blisters intact, but they are very painfull to walk on and unless you are independently wealthy & can afford 4 bearers with a sedan chair, you have to drain them. If you have to hold wound edges together, use butterflys or Steri strips instead of sutures.
