The Saint Martin is part of the central France style of knife, along with the Issoire, Yssingeaux or Laguiole.
The big difference is that this knife was not popular among the rural people but popular with the clergy.
Monks and priests liked its fineness to sharpen geese feathers and make quill pens.
The knife follows the center France style with a bourbon blade, end of the handle in form of a crow beak and a smooth mouche and the end of the back spring.
The handle often has top and bottom bolsters
An elegant knife, thin and easy to handle.
