The basic gaff for U3F is very old. Bob was the first to apply it to the 3 Fly effect and contracted Todd to make them for him. Todd offered a design idea which was worked back and forth between Todd and Bob.
Yes, the gaff is very old. And maybe Bob wasnt the first to apply it to a 3 fly effect. Before I met Bob I knew a guy in Michigan by the name of Jack Koopmans that was doing a 3 fly using the same gaff. Jack will vouch for this as will magicians in his area.
Bob gave me a very crude prototype and an idea credited to Robert Cabral on his video. The design was not worked back and forth. I made the gaff the way he instructed me the first time. Those of you familiar with the gaff will know what I mean when I say the rim stuck out past the insert coin in the original design and was highly visible. I believe Bob then proceeded to file all the protruding area away from the coin and remove a large portion of the face of the coin in doing so!
It was my understanding that he then gave this gaff to Chris Kenner and told him that I made it. I almost crapped my pants. Immediately after that I designed the gaff the way you saw it up until this point. There was no working back and forth, Bob was happy with my creation.
I guess I think of the gaff as my baby since I came up with a design that not only worked correctly, it also was near invisible, and proved to be quite durable. I am curious about the design change that BKM says they made to the gaff. Is it a significant alteration or improvement or is it still basically my design?
Also, should I continue to make my own gaff and sell it alone without a BKM routine? I pondered this after speaking with another gentleman last week who is also making and selling the gaff. Cheers.
