Hankostus are stout knives used for boning and trimming meat. These knives have pointed tips for inserting the knives into the cut and short height so the knives can turn to cut along bone, connective tissue, or fat. Hankotsus are sometimes unsharpened or obtusely sharpened at the heel to give a very strong edge for tough work during boning. Hankotsus are commonly asymmetrically ground so users should be aware that these knives may require a different set of techniques for sharpening and maintenance. Honesukis and gokujos are used in similar roles in the kitchen.
