From Wikipedia: mini survival kit is a small survival kit which consists of the most essential outdoor survival tools and supplies which are the hardest to improvise, craft on the spot, or replace. It is intended to be carried on one's person at all times, be appropriate to all environments, and be a comprehensive kit without being too large. Other personal gear will primarily offer additional serviceability and ease of use, but the mini survival kit should provide for the basic needs of a survival situation, followed by self rescue, assistance, or a return to normalcy in optimum situations. Two philosophies surround the preparation of mini survival kits. Some people like to carry a few, relatively large items such as a knife, matches, whistle, emergency food, water bottle, etc. Others prefer a collection of smaller but more comprehensive items such as rubber bands, paper clips, fishing equipment, lashing material, razor blades, etc. The decision of which technique to subscribe to depends on one's physical condition, survival skills, wilderness knowledge, and other factors.
