Stripper Decks
工作原理
A stripper deck has some cards trimmed, so those cards can be felt or drawn out of the pack by touch. The backs look ordinary. The difference is in the edge, not in a mark. This is not cut-out work, which scrapes the printed back so a white spot shows. A stripper card is a card of a different width or a different shape.
出现场合
Poker, and any game in which someone riffles or cuts the cards
有据可查
John Nevil Maskelyne describes convex and concave strippers in Sharps and Flats (1894). This entry uses that book. No modern casino conviction is attached to it.
