>>312144Take an old road bike tube. Something with a small diameter. Cut to the length of your handle on your knife. Slide around handle. Problem solved. Or you can get the Micarta handles...but they are crazy expensive for what they are. Else, make one out of wood, or 3d print one. Second, I think the allen bolts would be prone to corrosion, so a tiny dab of penetrox on the threads would be an easy and safe piece of mind.
