Multi-blades- American taste?

[Campbellclanman]

Question: Was it American cutlers who invented the patterns associated with the USA, like the stockman, or was it German cutlers? Judging by the previous posts the stockman is primarily used by Americans, but there's many German brand stockmans, both new and old. Presumably used mainly by Americans despite their origin.

Please correct me if I am wrong on this, I thought the early Sheffield makers introduced the main flow of knives to America?...before there were any actual makers in the America the Sheffield makers couldnt supply enough to the States?
