When I was in the Army, I carried a Case XX version of the Kabar for 7 years. What I had done was have the edge regound to more of a flat grind, as well as had the leather handle treated with some secret mojo sauce that some swamp rat from FLA developed that rendered it virtually corrosion and waterproof..
It served me well, and never jumped onto the kraton/rubber grip bandwagonas so many others did at the time they were hitting the market. To me a knife should be made of natural materials when it comes to the handle, so I never felt the need to change to one..
Cheers,
Serge
