It's a brand name used by Queen Cutlery; it's supposed to be their upper-tier line. And the best of the Schatt & Morgan is their "File and Wire" series, made with premium materials and in limited numbers. Of recent collector interest is the Heritage Series from Schatt and Morgan, exact reproductions of knives found in historic catalogs.
I have one of the File & Wire knives from Schatt & Morgan and the quality is very good, top notch in fact. My other Schatt and Morgan is a 2011 Heritage knife, and the quality is also very good.
What puts me off of the standard Schatt & Morgan knives, they charge premium prices but don't take the materials up a grade to match. They charge $100 or more for some knives, but can't afford to use anything better than 420 stainless? No Thanks.
