Back in the old days (1950's), it was customary to store cordage for emergent use by wrapping the grip of the knife with an initial layer of fishing line, followed by a layer of paracord and securing the whole with a layer of friction or electrical tape ( I don't believe that duct tape had been invented yet-historians?) The notion was officially presented in teh Randall Knife catalog as apprpriate treatment for their attack-survival model, which had a stainless steel tube handle with a watertight screw-on top. Anyone still do this?
