Stain-Shiv by Andrew Mayne

1.). A makeshift weapon
2.). A deadly game player with a sharp object

Based upon Andrew Mayne's Stab'd effect. Shiv is a disturbing presentation of Russian Roulette using a sharpened pencil.

One sharpened pencil goes into one of four envelopes - the others containing harmless straws. A victim is given a totally free choice and must eliminate three of the envelopes by stabbing their own body!

The final envelope is revealed to contain the deadly shiv!

Shiv is easy to perform and under the performer's complete control. No special props or gimmicks are required. It can be performed impromptu.
