I own both the BKM and the TT. Each has it's own value for my use. I have used the BKM for years when wearing a jacket. Always a strong reaction when signed card is revealed from zippered compartment. I like the aspect of no walllet contact with deck. Additional feature is the Mullica no palm, if desired.
I recently purchased the TT for daily use. Opened up possibilities of card (ie. business, credit card, etc.) production in impromptu situation. The appearance is disarming.
Both good quality leather construction. Consider your use....Pants pocket (TT) or breast jacket (BKM), Palm or no palm.
Enjoy your magic.

I have to buy a CTW effect (or C2W ).
I continue searching here and on other forums but I still can decide.
Maybe I will choose the Triple Threat because of his "triple" utility.

I hope I will be pleased
