Careful, There ARE some similarities BUT the Roberts fork is only similar to that from Richard Sachs, and the tangs with "suits of cards" is something Sachs resurrected because it was so iconic yet he couldn't get a reliable supply in modern times so he had his own made. There were a LOT of fork tangs (not to mention lug piercings) that used various card suits and combinations of them so when you wade in those waters...you come across some red herrings..,
