Doing some fencing a couple of weeks ago, anyway sliced my hands up with the barbed wire because I was in a hurry and foolishly didn't bother finding some gloves to wear. Most cuts heeled but some of the deeper cuts in the thicker skin kept opening up over and over which stung a bit. Tried band aids to no avail so being too much of a whimp to sew myself up with dental floss squeezed the wounds together and applied a couple of drops of super glue, pain gone almost instantly and cuts are almost heeled now.
