Last year I corresponded with them. Excluding the unreasonably expensive Cowry X Damascus stainless blade, I don't have as high an opinion of Fällkniven knives as does Joel.
These are not custom knives; they're production knives. Unless something has changed from last year, Fällkniven does not actually make the knives. They are the brand name. Knives are made under contract. I do not know if one contractor makes all Fällkniven knives. Where are they made? Without searching my archives, I want to say Japan, but don't hold me to it.
VG10 steel is not "best-of breed." It is a good knife steel, comparable to 154CM and ATS-34.
Laminating the VG10 with, I believe AISI 420, again don't hold me to this, significantly improves its ductility.
I'm not nearly as negative about Fällkniven knives as I have written. I believe they are excellent knives -- just not good value knives.
