ASP Chain Steel Handcuffs with Tactical Security or European Pawl provide a major advance in both the design and construction or wrist restraints. Frame geometry is the result of extensive computer modeling and simulation analysis. Strength potential has been maximized through use of an interlocking, unitized frame. The cuff structure is forged from high strengh stainless steel on custom built, high speed, progressive dies. Each restraint is then overmolded with ordance grade polymer under 75 tons of preasure. The Lock Assembly is unitized and replaceable. The Tactical Chain Handcuff was designed in the field. Input came from officers and instructors. As a result, this ASP design incorporates the practical features most requested by officers on the street. A stainless steel handcuff that weighs less than standard designs. 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. ASP Steel Handcuffs with Tactical Secuirty or European Pawl will provide increased control of violent subjects. 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. An optimized frame design was achieved thr
