Thirty years ago a Wilderness Survival expert put me on to the secret of how to dear deal with lacerations away from home. Apply a thin line of Super Glue to the two sides of the wound (be careful not to get your fingers glued together!) and within 10-15 seconds the wound is closed,the area anesthetized, water-proof, and no bacteria can get into the wound. Every emergency medical kit should have a tube of this stuff in it!
