Create fire in case of emergencies.

Even people who know how to create a fire without traditional fire-starting methods might not be able to do it fast enough, which is bad in case of emergencies. The TOPS Uberfire is a heat source used by the military that can provide intense heat without being vulnerable to water. It is encased in a small 2.0 oz tin can that can be carried in your pocket. This thing will provide steady heat when needed and very useful for cooking or drying stuff.
