Won my first French Razor. A Thiers-Issard with a jimped thumb notch. I have read that Thiers uses a hard steel that typically stays sharp for a long time. Seems like I have seen some with Solingen blades and some with (possibly??) Sheffield blades but I honestly have not studied these much.

Looking forward to adding another country's razor to my shaving resume. Am I going to be impressed with Thiers?
