What knife should I take if traveling?
Don't take anything that costs much:


You may have it taken away from you by border controls. In some parts of the world being able to confiscate nice things is a perk of the job. You want to enter (or leave) the country, you part with the knife. It could also be illegal to bring in knives over a certain size
Hostels are famous for being rife with theft. Having some nice folding knife just begs for someone to take it
Traveling is hard on equipment
It doesn't really matter anyway: who cares about the knife, anything will do. Ingredients and technique are what matters


If I were you I'd get a cheap, short cooking knife from some hardware store. Also make sure it looks like a cooking knife, you don't want anything that could be mistaken for a weapon! If you lose it, or it gets stolen, or broken, or you give it to someone who needs it more than you do then you just buy another cheap knife at a market somewhere. If you have an expensive piece of equipment it's just another worry.
