ZT14 (SK10) zak tool handcuff key, finish, black.
The ZT pocket clip key fits all standard Hiatt and Asp cuffs. Rather than fitting to a key ring, this cuff key has a pen type attachment that allows it to be clipped into a pocket. However, the best use for this key is to clip it into your vest.
This means that you'll always have it to hand and won't have to contend with it being attached to a load of other keys (not to mention the reduced risk of stabbing yourself in the leg with a large key in your pocket!)
The ZT range are manufactured in the US to an extremely high standard.
