Smith & Wesson - M&P Lever Lock Handcuffs, Nickel
Smith & Wesson Military and Police Lever Lock Handcuffs. They are standard S&W Model 100 handcuffs, but with finger activated double locks. Other manufacturers have had problems with finger activated double locks in that they can be accidentally activated too easily. Smith & Wesson has solved the problem with levers that move away from the direction in which you're cuffing so the lever won't accidentally be engaged.
