I wanted a handle with better purchase for my Benchmade Altitude, so I explored a few options before trying this. I didn't film the process because I wasn't sure if it was going to work. Plus, I had to work fast before the resin sets. In short, just like any homemade micarta where you layer resin soaked fabric, except the middle sheets will have cutouts for tang. Had an old shirt, so I cut 12 sheets - 8 straight and 4 with a cutout. Then, I simply layered them in order, pressed and waited for them to set before I sanded the extras off.
Thanks. Yeah, it's holding up nicely so far. I love how skinny the blade is on the Altitude, I just wasn't a big fan of the handle. Now that I shaped it up and remolded the sheath, it's a gamechanger.
