The infamous fork that de Blasio used to eat pizza at a Goodfella's Pizza on Staten Island sold at auction Friday night for $2,500.
The auction ended at 12:01 a.m. Friday with 6 bids that started at $1,000. The winning bid came from an anonymous bidder.
All proceeds will go to the Stephen Siller Tunnel to Towers Foundation, a New York-based nonprofit whose mission is to honor the families of the first responders killed on 9/11.
Foundation Chairman Frank Siller tells the Daily News that the winning bidder gave the fork back to Goodfella's Pizzeria.
Pizzeria co-owner Marc Cosentino tells news site DNAInfo "it's a nice piece of New York history to have."
While eating lunch last month on Staten Island, the mayor used a knife and fork to eat his slice.
That's a no-no for most New Yorkers, who are very opinionated when it comes to pizza. Most advocate using their hands to hold the slice, folding it over and then taking a bite.
Photos of de Blasio using the knife and fork were posted to Twitter and prompted mock outrage on several blogs and social media websites.
De Blasio later explained that he eats pizza the way they do in Italy. He starts with a knife and fork, then uses his hands.
He also noted that his slice had a lot of toppings.
