The key extension tool makes removing the handcuffs a lot easier. Well worth the money.
Finally somebody came up with an extension holder for a Smith and Wesson key. As many of you probably know. The S&W keys are about twice as thick as other handcuffs keys. But they fit inside the slot on this holder. I teach handcuffing and I have already used it a lot. It held up great so far. This is exactly what I have been looking for.
