I´ve been carrying a Shaman since it´s introduction and if I´m not mistaken, this is the 5th summer it is hanging on my jeans pocket. As I´m from The Land of Puukko (Finland), I immediately convexed the blade and couldn´t be happier. Now the knife is really usable in the Finnish country environment where wood still is the most common material to be cut. As for ergonomics this is the best Spyderco ever.
