nd something fairly inexpensive incase theft, loss or whatever.
but thinking maybe time to try a salt series!
Budget let’s say 100.00 or so if lost or whatever it wouldn’t hirt to awful bad!
Well, the most of the Salt series certainly fits in your budget. That said, losing a ~$70 knife, might still hurt.
For as short term as a cruise is, I think you'd REALLY have to try to screw up something like a Byrd Meadowlark.
Cheap- roughly $20
Handle material- FRN- salt water won't hurt it at all.
Steel- 8cr13mov, not going to win awards, but certainly serviceable and more that stainless enough to survive years on a cruise ship, never mind a week or two.
Size- nice carry size. Roughly that of a Delica.
Alternately, I'd go with an AUS8 Rat2, for pretty much all the same reasons.
Seriously, there aren't really many needs at all for a knife on a cruise. In fact, I was even thinking about knives like a CQC6 so you'd at least have the wave feature to use as a bottle opener since that would likely get much more use than a blade, and even then, I think they did away with glass bottles on the boats years ago...
Basically, getting yourself a "cruise knife" is a relatively frivolous endeavor, that said I've never been above frivolity.

Have fun.
