Man, you're undertaking a huge task I would not take!
As the colleagues above I found a few errors, for example in what concerns France :
- a useful tip : many "régional" (or régionaux) patterns are made by a several of makers. A hint for Laguiole : I could name more than 30 and would forget at least as much. Same for the Thiers, Normand, Massu, Tonneau, etc.
- Euskal Herria is the name for both sides of the frontier, the knives come from Pays basque, Laguiole is in Aveyron, the Bugiste come from Ain, not Savoie.
- some typos : Haute-Loire not Hauite-Loir, Aquitaine not Aquitene, Alsacien (or Massu) not Alscasien, Corrèze not Corezze, Garonnais not Garronais, St Amans is in Auvergne
- Coutebox, Berthier are retailers, not cutlers. Everybody make Pradels, the trademark exists no more.
- Allemand does not exist as a pattern, but there is a serpette allemande, Couteau à champignon is a mushroom knife and come from all the world, Cran d'arrêt is a knife with a lock.
- all that come from Baladéo is to be labeled Pakistan, these are not traditionals, just lookalikes.
- Perceval has its own range of knives, none is a real traditional.
A list of most pattern :

Your list has ommitted Hungarian knives. Look here (the patterns are in
BOLD), here again each patterns are made by several makers :

Hope this helps. Good luck!
