Quick Answer
Best uses for a multi-tool in survival situations include opening cans, cutting branches for shelter, and repairing gear. They are also useful for self-defense and as a backup knife. A multi-tool's value increases in situations where a full knife or other tools are not available.
Cutting and Sawing
A multi-tool’s blade can be used to cut vines for cordage, branches for shelter construction, and even small game for food when a full knife is not available. When sawing, use the blade’s spine to apply pressure and leverage, allowing you to cut through thicker materials. For example, cutting a 2-inch diameter branch may require 10-15 strokes with the blade’s spine.
Self-Defense and Repair
In a self-defense situation, a multi-tool’s spike or point can be used as a makeshift spear or for stabbing. When repairing gear, the pliers and screwdrivers can be used to tighten loose screws or fix broken parts. For example, tightening a loose screw on a water filter may require 5-7 turns with the multi-tool’s screwdriver.
Miscellaneous Uses
A multi-tool’s can opener can be used to open coconuts or other hard-shelled food sources. The scissors can be used to trim plants for medicinal use or as a makeshift pair of pruning shears. For example, using the scissors to trim a 6-inch section of a plant may require 3-5 cuts.
