Being at least 2 times a year in france, i started collecting them quiet early. I've got about a dozen Laguiole's in my collection. Quality is very inconsistent, because Laguiole is just a name for a certain knife style and like, say, bowies, there are cheapo taiwan POS knives as well as beautifully done pieces from master craftsmen. It depends largely on how much money you are ready to spend on such a knife.
There are 3 different classic styles of Laguiole knives. Single blade folder, single blade folder with a marlin spike and single blade folder with spike and corkscrew.
