Laguiole 12cm Picnic Knife with Brass Bolsters

My family is from very near the town in France where these knives are made. When a new Revel is born they are given one of these knives to celebrate the birth. I have mine and cherish it.

This is a Laguiole Corkscrew knife, also called a Laguiole 2 piece. 
The corkscrew was added to the Laguiole knife in the 1880s. This addition was the result of the sale of corked wine bottles in urban society, but also in response to the request by the people of Aveyron who had left to find work in the cafes of Paris. Cafe owners and waiters were to remain loyal to their traditions and were proud to use their 2-piece knife in the capital.

This Laguiole knife is entirely hand made in the village of Laguiole and features a forged T12 steel blade.
