Will you be using it on camping trips to your fully accommodated cabin or are you expecting to make shelter when The End OF The World As We Know It (TEOTWAWKI) arrives. Will you be carrying it on your person when you need it most. Anything past 9 inches or so and it starts to get cumbersome to use and makes it harder to milly comfortably. When looking to buy a Survival Knife, here are the factors you need to consider to make the best choice. Most survival knives are 5 to 12 inches in length. The size of a survival knife is a very important consideration. You want an effective tool, not a weird limp.

If however you don't have a role in the latest Rambo movie, you probably don't want to go past 9 inches.

Anything shorter and it might not be big enough to do the job. Obviously it can be smaller if your purpose is to whittle garden gnomes during your downtime at the cabin but should be on the bigger side if you plan on having a useful tool in any situation you may find yourself in.

Overall size, because size does matter.
