Corner Rounder


A corner rounder is used to restore the corners of playing cards, after the cards were trimmed on a card trimmer.

Most corner rounders were made form brass or bronze, with blades made of hardened steel. It should be noted that although sizes of playing cards (namely poker-size or bridge-size cards) are somewhat accepted as standards, the shape of rounded corners, of playing cards, is not mandated by any standards. So, different playing card manufacturers do not necessarily make the same exact shape of corners. For this reason corner rounders are not universal and a different corner rounder should be used depending on the brand of playing cards.


Below is a clipping from an old HC Evans Blue Book, crooked gambling catalog, showing a listing for a corner rounder that was sold at that time by the company.
