The Kendachi Monostar is both a solar powered fidget spinner and a deadly shuriken. The nice folks at R. Talsorian Games allowed me to toy with this design a bit for Cyberpunk RED, and I added an extending blade mechanism so the star doesn't cut your hand as it spins between your fingers. Once in mid-air, the blades extend while heading for their target. Groovy, stylish yet deadly. Good for a distraction too.
