In the extremely humble opinion of an 18-year-old, I would say stick with a proven favorite:
the ubiquitous KA-BAR. Why?
Inexpensive, around $50,
Easy-to-sharpen, strong, 1095 carbon steel,
Proven performance as can be attested by anyone in or formerly in the USMC,
Very useful blade point/shape,
Handguard, which may or may not be useful in your case,
and Replacements can be found somewhat easily.
The only thing is I might go with one with the Kraton handle and Kydex sheath as leather washers and the like might have a tendency to rot, although in my experience leather rot has never been an issue, at least in the short term-provided you apply vegetable oil or wax every so often.
Maybe I'm just a stupid kid but out of the 2 dozen or so fixed blades I've really played around with it'd probably be my pick off the top of my head.
