Press the end of the barrel and slide the cuff to separate the two halves leaving the smaller section attached to your keys or other item. Swiss made by the world renowned and reliable Victorinox brand from stainless steel and plated in nickel, this compact and useful coupling will not rust so you can use it in situations where it will be exposed to the elements.
