This type of weapon is made of an unidentified material that appears to be polished stainless steel. It is similar to a switchblade. It appears to be a small, thin, six-inch cylindrical device with a long rectangular switch or button that, when pressed, extends a long icepick-like protrusion that is used for stabbing. When this extension is released, the device emits a sound similar to a sudden jet of air being exhaled.
