This is a visually spectacular magic trick where a card is chosen, tossed into the air, and then pierced with a mini knife. You can find it by searching on video. It's a magic trick that is very well received. I also have a newer version, but I'm listing the older version because it's the one I prefer. The older version uses a force, so the number of cards doesn't decrease, and you can also do it without forcing if you wish. John Bannon also explained how to do it with a regular deck in a book a long time ago, so I'd like to include that part as a service document, although it's in English.
