The super rare and infamous "Butter Knife" font set. Named after the number 1 looking like a Butter knife. These jerseys were made to start the 08-09 season by a one-time Jersey producer. After 2 home games the NHL made the Flyers change their number font back because it was not approved

Only 1 for each rostered player exists in this style!

And  Lupul did score points in it!
