Many people seem to labour under the misapprehension that "Sabatier" is a brand of knife, probably because most Sabatier knives have "Sabatier" stamped on the blade.

It isn't and never was.

Sabatier is a style of knife developed by the French chef Sabatier, and has always been manufactured by many different makers.

Just like many different manufacturers other than CF Martin make "Dreadnought" guitars.
