I would have to disagree, there are quite a few quality knives in this price range.
They may not be custom fixed blades or be titanium frame lock flippers, but their still great knives.
I know you're thinking of a cheap modern folder or something, but who knows what the knife laws are there.
if you go to a hardware store or even Walmart you should be able to find the Victorinox recruit for about 15$.
It's an excellent knife, and I'm told ( I don't travel ) that it makes the perfect travel knife. Better yet It's more than just a knife, and you may end up in need of tweezers, a screwdriver, caplifter...ect.
There's even a member or two here who buy them at destination then gift them to people they meet when they're leaving.
