Shocknife SK-1 is a training knife capable of creating the acute stress needed to replicate a real edged weapon attack. Although the blade is incapable of cutting, it delivers a powerful shock when it touches the human body. The Shock Adjustment Screw has a low, medium, high and extreme setting. The settings allow the user to adjust the SK-1 to a shock level that best suites the type of training being conducted. Each knife comes with a custom foam cutout protective carrying case and accessories.
