Bad Brunette Girl With Handcuffs

There are two distinct subtypes of contemporary metal handcuffs: one in which the cuffs are held together by a short chain, and another, of more recent origin, which uses a hinge for this purpose. Since hinged handcuffs permit less movement than a chain cuff, they are generally considered to be more secure. A third type, the rigid handcuff, has a metal block or bar between the cuffs. While bulkier to carry it permits several variations in cuffing, e.g. Hiatts Speedcuffs are rigid handcuffs used by most police forces in the United Kingdom. Both rigid and hinged cuffs can be used one-handed to apply pain-compliance/control techniques that are not workable with the chain type of cuff. Various accessories are available to improve the security or increase the rigidity of handcuffs, including boxes that fit over the chain or hinge and can themselves be locked with a padlock.
Handcuffs may be manufactured from various metals, including carbon steel, stainless steel and aluminium, or from synthetic polymers. Sometimes two pairs of handcuffs are needed to restrain a person with an exceptionally large waistline because the hands cannot be brought close enough together; in this case, one cuff on one pair of handcuffs is handcuffed to one of the cuffs on the other pair, and then the remaining open handcuff on each pair is applied to the person's wrists. Oversized handcuffs are available from a number of manufacturers, as are juvenile-sized restraints, though none of the latter in current production are approved for use by the United States National Institute of Justice.
