What Type of Knife Should I Carry?

If you plan on thru-hiking or backpacking you should really carry a knife with you. For most hikers, the affordable and lightweight Swiss Army knife with a lot of useful functions is the best option. There is little need for a large, heavy knife when you actually get on trail.
If you are traveling by plane you will need to check your knife in a bag. TSA does not allow knives to be carried onto planes, no matter how small they are!
