Nordic blades share more in common with English and American blades than they do with continental European blades, and are made of hard steel that's beveled by grinding. The Øyo blade is a fully forged laminated blade, which is revealed by the chips towards the heel of the blade--the glassy hard edge steel chipped in whatever hard impact it experienced before I got my hands on it and a "shelf" of the supporting cladding iron remained. It's a slim, light blade with moderate rigidity and a springy quality to the blade, in a good way. The Hamre is a Norwegian blade that's interesting in that it's press-formed in two separate parts that are welded together. Hamre is still around and produces both forged blades and pressed blades today. I have yet to find out anything about the manufacturer behind the Øyo blade but its form is classically Swedish and the fact it was acquired from a fellow here in the USA is notable.
