kullenschiff edge
n.β Β«Santoku knives are generally shorter and more delicate than French-style chefβs knives, with a broader blade and often whatβs called either a grantonβor a kullenschiffβedge. What that means is that the blades are fluted with little air pockets and super sharp, preventing food from sticking to the blade of the knife.Β» ββEats & Drinks: Santoku knife takes special care to sharpen” Detroit News (Michigan) Aug. 3, 2006.
