I recently purchased the Ka-Bar D2 Impact Knife and I absolutely love it. However, I'm not a big fan of the handle, and would like to wrap it with paracord. The only thing is, the cord slips off the end of the knife. I noticed that Striders fixed blade knife and Spyderco Kumo has this friction spray-on on the handle that prevents the cord from slipping. Does anyone know what it is? Spray-on or some sort of frictoin tape would work for me. Thanks
