I didn't want to keep using my Spyderco or Leatherman for opening bags of rock salt for the water softener because surface rust was an ongoing issue (despite immediately cleaning them). On Walmart's website I found this Saltwater Bait Knife. It reminds me of a Mora. It arrived with a decent edge and as expected the blade is a little roughly finished but for three bucks it's a good deal for a decent utilitarian knife. I leave it outside by the softener. No rust so far but I don't really care if it does rust.
