Personally, I have not really seen any males knit but I'm sure they are out there. The reason I think that they do not knit is because it seems like a womens' hobby, something that was feminine and not very manly. But it is pretty cool to see that in other cultures, things that may seem womanly here can be for both genders.
But I think that in Canada, something that both women and men can do is design clothes, though not alot of males do that or have the right eye for it, males do own their own fashion lines and most of the time they even design female clothes. :)
