I am a whitewater kayaker and have been looking for a new knife for my PFD. I have an Atlantic Salt folder and love it, but would prefer a fixed blade, sheepsfoot serrated with a retentive sheath I can mount on my PFD. The Caspian series looks like it would fit the bill nicely, however obviously that has been discontinued. It looks like a great design, I am surprised they are not still being made. I would think a fixed blade Salt series river knife with H1 steel like the Caspian, perhaps slightly shorter length with a sheath compatible with PFD lash tabs and in the 40-80 dollar price range would totally dominate the river knife category, with most current options having either inferior steel, design, and/or sheaths with rivets that rust easily and don't retain the knife, such as the NRS pilot series, CRKT Bear Claw, etc.
