It`s a fun thing to use in many ways.using a old 16 OZ coke bottle is the #1 way I use it,and gets good results at partys.the rubber band is short lived though even after carefully deburring the edges on the fold peaces.Is there anny way to get the system to last longer? so I don't have to worry about a band snapping during a show LOL. I have a good DVD set that magic makers produced that has fun uses for the Gaffed coins. I have a Johnson expanded shell half on order to add to my collection.I cant wait to practice some fun tricks with it.

I have a David Roth video, where he says he uses two rubber bands most of the time with the gaff and specifically for that reason.....

A great video.

I don't think there is any way to help make the band last any longer unless you would remove the band when not in use. Apart from that, probably the safest way would be changing the band before a performance. Then you can be pretty sure the band won't break. But if you perform this effect every day, I can see where you wouldn't want to do that.

Changing the band is advised in using this gaff.The good effect is worth the reward to use this high meintence coin.I do only use it part time.I use most of my low meintence gaffs a lot.As fingers noted about using 2 bands hides the slit better but could make it harder to fold when getting it out of the bottle?
I was thinking of trying a spring that is simular to what they use on a machine lip seal,but couldn't find a spring small enough yet

The spring idea sounds pretty good to me, if you could do it Enginemagic. It definately would have to be small though.....

I have notice that. Someday I`ll come across a machine that I scrap out or be repairing that has a spring that I can use. I`m alwase working on ways to improve products to make them work better for the public,and industry.
The magic world can use a gaffed coin that works as well,and is long lived as a oil feild engine/pumping unit. LOL
