The other knives have a rampant (rearing and pawing) lion marque. As a matter of fact, you might say the lion is "K" shaped. The blades are additionally screened "Sabatier," and "Made in France," but without reference to any specific maker. The handles are NOT engraved or otherwise marked.
I'm pretty sure these are made "OEM" by one or more of the regular French Sabatier makers with the purpose of marketing them outside of France; and/or are excess or other NOS, relabled. I also believe the U.S. importer is a company called "Cuisine de France," but I may have conflated the knives with other stuff, so am less certain on that.
...
At any rate, I had a couple of those "Lion Rampants" which I purchased through Amazon around 2001, or 2002, and believe they were made by K-Sabatier. They sure felt like it. I may even still have one -- I'm not sure the logo's faded.
