You are probably referring to Thiers-Issard, which is indeed also considered good. I have no experience or much reading done on those, but Tim likes his.
K Sabatier is very much a “real” Sabatier also though, they are the ones I have, you can read about K-Sab history here for example, at their official site:
They also have put this one up:
In general what I have seen is that Thiers-Issard and K Sab seem to be the two most commonly recommended Sabatier brands of today. I haven’t had plans to get to know all Sabatier brands or anything like that. I chose K Sab mainly for their long history and because from them I had the opportunity to buy old stock knives in an easily accessible form and unused.
I would honestly be interested in getting one modern 10 inch Thiers-Issard also, if just to compare, but getting one might just open up a new rabbit hole and soon I would then “need” something else also. I have essentially too many knives already and have been toning things down…
