My sharpest knife, easily, is a Helle Symfoni in 12C27 stainless. Following closely and, on odd days, surpassing the Helle is my Bark River mini-Canadian, a convex grind in A-2. Next would have to be an Enzo Trapper in O-1...scandi ground.
My Rukus is one sharp knife, but it sits in a collectioan of very sharp knives. It is not the "genius" of the class.
