Hand Pi = Helping Hand + Pi Day
Hand Pi's 'helping hand' ideals stem from the inherent values of the original brand and those people who made it happen. "Hand Pies" were (and still are) a specific grilled sealed sandwiches that were made in a camping type utensil (pie iron). The Toas Tite like "Hand Pie Machine" was unique and way ahead of its time in that it toasted an image of a logo (the hand pi) on the sandwich.
Hand Pies started at the Renaissance Pleasure Faire in Novato, California in the early 70's. "The Faire" was queen of the then emerging industry of 'theme events.'
