If back alley knife fights get in the way of juggling your job and family, you might want to consider picking up the Shocknife. The Shocknife is a training knife that delivers a localized shock of up to 7,500 volts. The blade itself is incapable of cutting, and the shock will deliver only temporary pain, not serious injury or incapacitation. The blade is mainly targeted at police training exercises, offering a drastic improvement over the commonly used wooden and rubber training knives. A case of two goes for $900, and let's face it, nightly knife fights provide an easy and quick way to settle those pesky dinner table arguments.
