I have a Camillus Pilot Survival Knife, circa 1967. (For ID purposes, it looks most like the #5733 on the Camillus website.) It has some wear, minor rust, and the guard is just a little bit loose. I would like to take it apart, clean it up, and put it back together with the idea of treating the steel and leather separately, and ending up with a tighter fit in the handle/guard area when I'm finished. My question is: how do I get it apart? Is the "hex nut" style butt really threaded onto the shaft? Can I put it in a vise and torque on it with a wrench? Or is that nub at the end actually the end of the shaft, through and swaged to the "nut"? Please keep in mind: this is not a knife that I ever want to sell. I am not a collector. I'm going to keep this knife, use it forever, and don't care if it's in original condition. I'm even willing to shorten or lengthen (slightly) the handle if necessary. All I want is to improve it's condition and feel... Please pardon my ignorance, and thanks for any help!
