BINGO DUDE!

I have a set of the "high security" 104's with the funny key. The other set my son has are the 110's.

I had modified one of my 104 keys to open the "standard key" cuffs and still open the 104's as well. So...I guess the only remotely strange set I have are the 104's.

Thanks scha....you nailed it for me. I use to get a kick out of some of my local COP buddies that could not open my cuffs with their standard key.

Thanx to all, but one more question...are these usually stainless steel or nickel-plated. I am pretty sure the 110's are stainless, but I am not sure about the 104's. I am not going to file a spot off just to see and sometimes the magnet trick doesn't always work.
