Also known as a Japanese Chef’s Knife, the Santoku is a wide blade knife with an overall thinner spine and taper than a French or German style Chef’s Knife. The thin taper (or blade thickness) is lengthened to give it maximum precision when slicing. The 7" Santoku Knife is one of the worlds most popular knives.The spine runs parallel to the relatively flat cutting edge and only curves near the tip to create a broad bladed knife similar in shape to a cleaver. The alternating kullenschliffs (a.k.a. kullens, hollows or grantons) on each side of the knife reduce drag and prevent items from sticking to the blade.
