survival knives

A straight blade knife is much better in a survival situation than a folding knife. A folding knife has more potential to break when using it as a tool it was not intended for. Try to pick one that has a tang (the part that the handle attaches to) that runs the entire length of the knife, handle and all. When constructed this way they are much stronger and can withstand much more abuse. You don't want to be working with broken equipment in situations like this. That would just be asking for an accident to happen. This is not a good time to be injured from a self inflicted wound.

A good multitool from gerber or leatherman is still the best choice to have if you have to choose, but I would rather have both a good knife and a multitool on hand if possible.
