Maybe a Spyderco Military. For sure, a large folder with a large hole, or an automatic (where legal). Not sure how corrosive resitant the 440V is.
I much prefer a fixed blade in a quick sheath, i.e. kydex, in a rust resistant steel, like 440A.
With neoprene gloves and cold hands, tidal surge, etc , etc, a folder may be too slow , and easy to drop while opening.
