The handiest tool you can have on you at all times in a survival situation is a good fixed blade knife. Fixed blade knives are better than pocket knives because they’re much stronger and more versatile.
Due to their structure, pocket knives are much easier to break than fixed blade knives, especially at the pivoting point where it flips. Fixed blade knives have tons of uses if you know how to use them, ranging from fighting and hunting to bush crafting.
You can make shelter, get food, and defend yourself all with one solid piece of equipment.
The best use for this knife is bush crafting. Bush crafting is the art of using wood and other materials found in the outdoors to create useful tools and shelter. For example, you could carve out a fishing spear from a tree branch to spear for food, or even to defend yourself from predators. You can also use the knife to collect wood for fires, or to collect branches for the roof of your shelter.
