I have a bike inner tube stretched up over the handle of one of my 14 inch Fiskars.
Makes the handle "grippier", lol.
Been tempted to make an emergency kit to slip into the hollow handle, maybe some matches and/or a peanut lighter, PCB firestarter, thin ferro rod and striker maybe even a Vic Classic or Leatherman Micra and a small amount of paracord.
You could do up a kit in a long thin plastic bag and seal the ends with a twist tie or use one of those kitchen dohickeys that melt seal the seams of plastic bags. Use decent strength plastic bag material and leave enough material at the one end so you can easily grasp the bag and pull it out of the handle.
Cut some cork or wood to fit the end of the handle to act as a plug, cut the plug so that it has a hole running through it that corresponds to the handles lanyard hole.
Then run some paracord through the end and tie it off so the plug won't fall out.
