Safety pins - excellent multipurpose item.

Wound closure? From my very limited understanding, that's not something you want to do in the field; seals the wound up and lets it fester. Better to let it drain after you've stopped bleeding (overlap that avulsion with the host limb; don't just lay it back in place).

But if closing a wound is something you want to do, tape (and a lot of it with 4x4s) will do nearly as well as a suture kit.
