Sponsored: Used for hollowing concave forms, these hook knives are designed to take a paring cut, permitting excellent control. The steel blades come sharpened and honed to a keen edge, and the thick 4-1/2″ long beech handles have an oval shape that fits comfortably in the palm. The roughing blade has a more pronounced curve (approximately 1/2″ radius) for rapid material removal; the shallow-cutting blade is curved to a 1-1/4″ radius for finishing cuts. The sets are offered with one roughing knife and one shallow knife in right-hand and left-hand models. You may need only the version that suits your dominant hand, although they are complementary, since having both gives you greater flexibility to accommodate changes in grain direction.
