I wanted a longer, slimmer handle for my machete, and for the challenge, I thought I'd do it using only plastic scraps and paracord (also some used tape from the scrap bag).
Step 1: Get Rid of Old Handle.
I dremeled through the pins holding the current scales in place, then pried of the scales. The front pin would not come out, even with hammering on it, so I simply cut it close to flush and moved on.
Step 2: Twist Rudimentary Cordage for Initial Wrap.
Pliers and teeth work for this.
Step 3: Wrap.
Step 4: Cut Plastic Into Strips.
Step 5: Mummify and Secure With Tape.
Step 6: Gather More Plastic for a Palm Swell.
Affix via additional mummification and tape.
Step 7: Black Tape and Paracord.
Okay, so I cheated with the black tape, but I didn't like the white showing through between the loops of paracord.
To start my wrap, I secured the paracord with a barrel knot.
Step 8: Voila!
I tied a simple knot at the end of the wrap, and added an adjustable lanyard.
