Zak Tool #11-LG 5" Large Grip Round Swivel heat treated stainless steel handcuff key. Keyring included. Opens all standard handcuffs. Made in USA and has a lifetime guarantee.
So far its been great. I was looking for a key as long as my pen key and this fit the bill. It works with my big hands.
Positve, this key keeps my hands that much further from the badguys hands. Downside, if your badguy is large, you wind up stabbing them with the double locking post. Carry the standard key and this one.
