Last year, I supplied three knives to the tournament table, and we barely made it to the end with a usable pair. I wanted a fourth knife for this year, so I gathered parts. I considered using the same thin ABS tube for the handle but decided on clear polycarbonate tubing.
The electronics came from a damaged knife, and I already had an endcap. Most of the work came from modifying the training knife. I cut off the handle with a jigsaw, then shaped the remaining plastic with a razor knife. It had to fit inside the polycarbonate tube. I drilled seven holes in the tube to hold the blade, endcap, and switch, then assembled it. The final assembly step was adding aluminum tape to the blade.
