Smith & Wesson M&P Lever Lock Handcuffs. They are standard S&W Model 100s, 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. All current inventory is the new riveted design. Available in nickel or Melonite. Melonite is temporarily out of stock.
