Basically, this bayonet is very sturdy and I wanted to find out if I
can sharpen its blade so that it could be usable as a general purpose
knife, to keep close to me in my truck. Just in case.

Depending on condition it could be worth $100 or so.

Also, does it need to be wet sharpened or a regular bench grinder is
OK?

I think they can be sharpened quite well with a fine single-cut file,
drawn lengthwise.
