I'm interested in the Thiers Issard Le Grelot Straight Razor 6/8", Ebony Wood Handle here:

Thiers Issard Le Grelot Straight Razor 6/8", Ebony Wood Handle | Fendrihan Shaving Store

My question is: what is the difference (if any) between a Thiers Issard Le Grelot with the "Le Grelot" trademark on the tang versus the "Thiers Issard" trademark?

I'm waiting for a response from Fendrihan, but I thought I'd ask here as well.
