razor-blade-sidekickThe NYPD continues their efforts to educate officers and the public on some of the latest developments in homemade and concealed weaponry, everything from “knives inside lipstick containers to steering wheel security devices that can be converted into shotguns.”

The latest “unofficial” department missive suggests criminals fashion shivs from pieces of broken mirror, hide a razor blade in a cell phone battery compartment, and for the more technically adept: turn an ordinary cell phone into a stun gun. NYPD sources claim that heavy police presence and pressure on guns often accounts for these DIY weapons, and may explain why stabbing fatalities increased 50 percent as shooting deaths dropped last year.
