Abstract: An anti-crime device, known as the Anti-crime Spike-needle, is an inconspicuous device that is attachable in any quantity to fur-coats and other garments and articles, and is harmless to the wearers and users of such garments and articles, but it can sting and injure anyone who uses force or unnecessarily heavy pressure to hold, pull, push, detain, or strike the wearer or the user thereof. Its main components consist of a spike-needle and a hair-like resilient steel wire, the former's needle-sharp point is prevented from touching anyone who is friendly by the latter which encircles or stands next to the former. When a pressure greater than normal or friendly is applied on the garment or other article equipped with the device, such as by a criminal, the resilient hair-like wire or wires yield and expose the sharp point of the spike-needle and discourage and even stop any further overt act against the wearer or user thereof.
