Since hinged handcuffs permit less movement than a chain cuff, they are generally considered to be more secure. Hinged cuffs can be used one-handed to apply pain-compliance/control techniques that are not workable with the chain type of cuff. Because of their conical bow geometry, the cuffs fit large subjects, yet still control small wrists. They are easily carried, rapidly applied and have a clean, smooth, finished appearance. The four point connection system allows the cuffs to fold flat and yet be worn over belts of various thicknesses. Because connecting rivets are integral with the side plate, they cannot be driven out. As with all ASP products, the design for these Hinge Handcuffs originated in the field. ASP Trainers surveyed instructors and officers throughout the world. The most desirable handcuff features were listed and categorized. The result is a handcuff unlike any other. The design introduces features, construction and materials that are innovative, real world and strong.
