2020-02-27 (Th) Electro Knife for Simulated Combat EleKSCo

A lot of the parts which inspire and compose my projects come from a local surplus store that features signs made by employees. I compromised with the following warning to not use anything in the box for fighting.
Tag in a local surplus store

Enough background

The previous handle was a good starting point, but it had issues, like the switch that poked through the far side of the handle, and it was awfully long to be a "knife." A low-profile switch with a hard tactile feel came from the local surplus store. For now, it was easiest to press it with a bolt running through the PVC.
Switch and plunger

This time, the "blade" and handle would be one part instead of trying to marry two dissimilar parts. To hold everything in place the switch was covered in double-sided tape, and the wires were wrapped in helical wire wrap. The tape was not a permanent solution.
Wired switch with tape

Two strips of aluminum tape were applied to the sides of the PVC pipe so that there was a gap at the top and bottom where electricity could arc. High voltage wires on the far side were held against the tape with a rubber band. Again, not a permanent solution.
The business end of the baton

The PVC was long enough to act as a handle which would contain the battery and a blade where the high-voltage generator would sit and connect with the aluminum tape. Putting the generator on the far side would allow the knives to be balanced by carefully placing the everything a certain distance from the switch. It turned out that keeping everything in place was harder than anticipated.
Baton parts

The system worked and generated sparks across the aluminum tape gap. In the video, the electrical arcing sounds more menacing than hearing it in person but of course, electrical microphones would be affected differently than fleshy ears.
