Ok, so... The Opinel is the very first one in the collection. The knife was sharp and had a burr down one of the sides. My first move was to try to remove the burr with a Spyderco UF stone. (fail) My second move was to strop the blade on a Knives Plus white strop block. (razor sharp in 3 minutes) : ) I guess the convex edge likes the strop. Very impressed with the Opinel so far.
