Oh, it was a male craft. In fact, it was seen as a man's profession for hundreds of years. The knitting guilds of old old old are all male, like the tailor guilds, cobblers, etc...
Women would do it at home but it was for crude clothing. The educated knitters who were doing fancy stockings and the rest of the majority of knitters were professional males.
It's funny how things changed in the last 300 years.
