Hi David Martin,
My name is Jerker Andersson and I work technical support and business development for Sandvik. I would like to clarify a thing or two here, just to make sure we have no misunderstandings.
ALL Sandvik alloys are made at our steel plant in the town of Sandviken in Sweden. We are a company of about 47000 and have operations all over the world, also in the US. But for knife steel everything is made 100% ready in Sweden. From melting to finished cold-rolled, slit and packed product.
Sandviks goal is to make the best possible knife steel in terms of performance and productivity (read fine-blankable). That is why we dont offer AISI standards like 440C, 420HC and so on. We make our own the way we believe they give the most possible value to producers and users. On a personal note I think that Sandvik steel and BUCK H/T is a fine match. I'm sure BUCK will make the most of our steels the way they make the most of 420HC today.
Here is a link to the hardening guide I wrote last year. I contains alot of info both general and specific about knife steels, heat treatment and so forth.

Please let me know what you think of the steel, either here or at the reviews and testing forum. All feedback is value for our improvement.
I hope you like the BUCK/Sandvik blades.
Regards
