Maintenance of your Laguiole mechanism
A folding Laguiole has a mechanism. If it becomes difficult to open and close the blade, lubricate the mechanism, like a car engine (you will avoid premature wear of the mechanism). Use a type 3 in 1 oil or WD 40. Insert a drop of oil with the blade closed between the blade and the spring at the blade axis. Open and close the blade and wipe off the excess.
