What is "tims industrial strength gaff?" Oh that would be revealing. Actually what does this gaff allow you to do? Can it be made at home? Reason I am asking is because the trick list of the first book of AoA says that it uses this gaff.
Tim's industrial strength gaff, refers to a gaff card which allows for a very clean production of four coins.
Thats all I shall say on the subject, due to the nature of the effect.
