Hi, I don't know hone master in France, but if you will send in outside EU you can consider Ukraine, I can recommend you really great master whose quality I can guaranty.
Also as we had huge devaluation of our currency (Hrivna) prices in $\€ is really low. Honing only 10$ and return shopping cost also low (don't know right now exact price).

Actually I will be in France in start of March, but only in Meribel and due to long break in SR shaving I have now lack of honing experience.

I also send my razors to above mentioned master
