Smith n Wesson Black Hinged Handcuff – 10064. The Smith and Wesson model 300 hinged police handcuffs are more restrictive than standard chain handcuffs. The model 300 is constructed of carbon steel and is nickel plated. Satin nickel plating provides corrosion resistance and makes the handcuffs appear dull or cloudy to prevent glare in tactical situations where cover is required. The hinged design safely restricts movement providing more security for officers.
