Just tried to get the manager at Via Tribunali here in Portland to order me a dozen, no dice.
Got in touch with the US Pintinox sales rep to see if I could order some. Turns out there are none in stock in the US, and ordering just a dozen from the warehouse in Italy may prove problematic. Might need to order a "unit", or 120 knives. Might be a about $6/piece, so I might need to organize my fellow pizza nerds to pool together on these. I'll know the details later next week.
Stay tuned...
