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. S&W 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. Available in nickel or Melonite.
