I remember watching a televised game here in NY in which Flyers goalie Don "Smokey" McLeod was using a stick with a curved blade, and it was the first one I'd ever seen.
Looking up his records, he only played 4 games with Philly in the 71-72 season, so I witnessed a rare occurrence. I don't recall if it was a "Game of the Week" telecast or a game versus the Rangers; perhaps our Flyershistory member can verify that.
Of course, he moved on to the WHA the following season where the curved blade helped make him quite a playmaker. Although he didn't register an assist in his first season with the Houston Aeros, he went on to record 43 assists in his next five WHA seasons, including a high of 13 in 1975-76 with the Calgary Cowboys.
Can anyone recall an earlier instance of a goalie with the curved blade??
