Hi. I have a vague memory of a cocktail sword through bill penetration but have no idea if it was in a book or a marketed effect. Any help would be most appreciated.

Michael Close had a toothpick-through-bill effect in Workers 2 ("Rubik's Dollar Bill") that could be adapted to a cocktail sword.

There is an effect called Cocktail Bill Penatration" by Ken Kuroki on page 53 of Kaufmans 5X5 Japan may be that's what your looking for although its a pen/pencil thru bill not a sword.

I don't know if this is what you are looking for, but there is a method by Johnny Hirose, where a pen or cocktail "sword" could be used. This uses a post-it note covering part of the bill (but is totally different from Sankey's Dough). This version can be found in Joshua Jay's Magic, the Complete Course

This was my first thought as well. It is a nice illusion and the swords would work fine for it.
