I was shopping to replace a key I had given away to a friend as gift, and saw this while I was browsing. I had just recently watched a documentary on the 1993 riot & hostage situation at Southern Ohio Correctional Facility. I am a corrections officer, and I thought it couldnt hurt to have a backup key tucked away in my belt keeper in the event that I was ever in a situation where I was cuffed by an inmate. The only downside is that I discover that I cant snap down both snaps on the belt keeper I keep this on tucked in, so maybe future productions could have the openings a hair longer & wider so that the key is more secure. Used this key during my tactics training this week, and other COs and Patrol Officers thought it was pretty neat. Good product, just needs a tiny design improvement.
