Looking for jammed handcuffs

I am looking for a pair of used handcuffs with a sticky lock or wore down key. I would like a pair of handcuffs that work but you have to play around with the key for a while to get them to open. Kind of like having time release handcuffs. If anyone has a pair of wore out but not broken handcuffs they would like to sell please email me. walterwayn@yahoo.com
