THE SHORT ANSWER IS THAT MARFIONE, TONY MARFIONE, IS THE OWNER AND DESIGNER FOR ALL MICROTECH PRODUCTS, THE COMPANY, ETC.
BY DEFINITION, HE USES THE MARFIONE NAME TO DISTINGUISH HIS "CUSTOM" PRODUCTS FROM THE CORPORATE LINE.
This is a very thin line, but in many cases, Tony makes some knives pretty much by himself and sells them within the Marfione brand for fiscal reasons.
I think the advice about using only Credit Cards is sound as there have been many instances of slow, delayed and even never deliveries of both Marfione and MT products.
All work now is done in the Bradford, PA plant, as the Vero Beach, FL factory closed some time ago. (Typically, Vero produced knives carry a higher value than the newer, Bradford- produced stuff. )
Promises are often made that cannot or are not kept, so protect yourself.
The credit card tool thing is still, no matter how you look at it, pretty much a gimmick and you could make one for about 2 bucks with a grinder and some, any, metal. Sage advice is not to carry one of these through TSA security though as they look at it as a "weapon."
