A lot of those Finn knives use blades from the same source but with their own handles. Nothing wrong with them, good basic working tools. The carbon models are something close to 1095 and I think most of the stainless blades are Swedish 12C27.
Custom Finn knives wise I like Jukka Hankala and Pekka Touminen. I own 3 Hankala and one Touminen. All four see regular use.
