knives are a pain to sharpen, but don't rust as fast. YMMV

Titanium blades are tough to sharpen but retain (I'm told) a wicked edge
when you finish. Titanium isn't a really strong metal on its own, but, like
aluminum, almost all useful alloys are much stronger/harder/tougher
than the native metal. Wenoka makes a titanium knife that is not too
expensive and has lots of "cool factor" to it (yer basic Blackie Collins
blade). Plus a polycarbonate handle/sheath. Tanto tip. Fishing line
hook.

I know nothing at all about ceramic (e.g., Boker) knives.

Ceramic knives are too brittle to trust in a rescue situation. Great in a
kitchen, though.

Still prospecting for the unobtanium mine.
