Norlund axes were initially designed for the Canadian market and so, unsurprisingly, have the standard Canadian eye, which is larger than the standard American boys' axe/hatchet eye. Oxhead Iltis Canada, Garant, Walters' etc. will be the same. To me the American boys' axe eyes seem weirdly small. Having a larger eye on a light head makes for better geometry in my opinion, and is part of why Canadian patterns like the Spearwell (etc) Slimline, Garant Canadienne, Muller Biber, and Ochsenkopf Iltis Canada are such great little axes to actually use.
