I have seen this product around and it will engrave handcuffs once a holder is created for it.
It is out of the price range for most people but if one is engraving tons of keys or cylinders, it might be a viable option.
I am not sure why anyone would engrave their handcuffs if they are in a collection. If used for marking cuffs for use in a police or sheriff department or in a detention facility, this would make sense
