The Smith & Wesson's model 100 handcuffs are the carbon nitride finish version of their standard model 100. Formerly called Melonite, the carbon nitride process hardens the carbon steel used to construct these handcuffs and also turns them black. The carbon nitrite process is a case hardening process that leaves a relatively thick, corrosion resistant, hard black surface. These handcuffs feature a more corrosion resistant surface than traditional blued handcuffs. Black handcuffs are also preferred in tactical situations day and night where users want their gear to be as non-reflective as possible. MEETS NIJ STANDARD 0307.01
