Re: [Paddlewise] PFD knife or hook? Trying to prevent rust

I have a knife that I found on Mt. Hood. It appears to be some sort of
dive knife made of a single piece of metal, with circular holes punched
in the handle, and came with a plastic sheath. It is dull as an 
astrophysicist
on crack cocaine, but has not a speck of rust. I use it as a letter opener.
