This blade is thick on the spine (tapered spine) that works for cutting or split into the ingredient like an ax, and the tip side becomes thinner on the spine, and the thin tip makes easier to slice into the ingredient. To slice into the ingredient from the tip side to the heel side makes easier to cut into the ingredient easier too, and it is easier to come off the ingredient from the blade without stuck on the blade. It is an ideal shape of the slicing kitchen knife. It is also wide blade on the heel side.
