Question: size of knife
Document: If you are familiar with the French Laguiole knife, seen mostly in cooking magazines as fixed blade steak knives. This is a great folding style example of this knife. A pocketknife!
Beautiful knife and come with a pretty nice sheath, although it seems a bit too bulky for the thin knife. Amazing price, just wish shipping was less to America. But it came in about 7 days
I have purchased three knives from this company, this is the only folder I've purchased from them. The fixed blades were very nice quality, the folder was not as nice.One problem is pricing, feel like a sucker buying when I did. Seems after I buy each knife the price drops by as much as 50 + percent.
Gave this to my mom for her purse. She was very pleased with the beautiful combination of wood and brass.
Answer: yes
