Concertina Trip Mines

CONCERTINA TRIP MINE. (See also, TACTICAL DEVICES) The concertina trip mine is a more malicious and powerful development of the non-lethal version of the device patented by Samuel McCollin in 1879. Featuring an explosive spool of concertina wire, on being tripped the device expands rapidly, snaring the victim, or obstructing a choke point. Rather than a deterrent, its function is far more offensive. A trespasser, once having tripped the wire, is forced to find a way out before the traps setter finds them, for surely their intentions would be deadly. Similarly to the tamer alert trip mine, the concertina trip mine did not see mass production, but was passed from individual to individual as a schematic design that could be built at home.
