Sakai Kikumori ‘Nihonkou’ 150mm Honesuki kaku. Carbon tool steel with riveted pakka wood handle. HRC 63.

Made right-handed, honesuki kaku are primarily designed for breaking down poultry. This Japanese boning knife has a thick, triangular, self-guarded blade. These type of honesuki are great for sliding through joints and going through smaller bones.

Sakai Kikumori's Nihonkou line are reasonably priced factory made carbon steel knives with a carbon content of .95%, hardened to approx 63 HRC. Nihonkou knives’ thin mono-steel blades are super easy to sharpen and get a nice edge that holds well.

Thin SK mono-steel blades cut very nicely with their thin profile and are super easy to sharpen and get a nice edge that holds well. They are ideal for the professional or home cook who is looking for a great workhorse with easy sharpen-ability.

Sometimes among comparisons of Japanese carbon steels SK family steels are viewed as inferior to more refined shirogami or aogami however when making single steel knives SK has its advantages. SK steel rusts slower than many other carbon steels like aogami or shirogami and has a good toughness which benefits a thin mono steel knife.

This is a non-stainless carbon steel, it should be mentioned that extra care is required, it should be washed and dried immediately after use. It will develop a dark patina with usage, but any orange rust should be removed with a light abrasive.

Sakai Kikumori was started in 1926 and draws on Sakai's 600 year history as the major center of traditional Japanese cutlery manufacturing. They work with a large variety of Sakai's best smiths, sharpeners and small factories to offer a wide variety of knives ranging from traditional materials and styles to more modern, western influenced styles and materials.

This is a carbon steel knife. Carbon steel is expected to develop a dark patina with use. It needs to be hand washed and towel dried soon after use. Do not air dry. Do not put it in the dishwasher. Long exposure to moisture and debris will result in rust. Any rust development should be removed with a light abrasive.

Twisting, scraping and heavy use as well as use on hard and very dense objects can lead to edge damage. Use on a quality wooden cutting board will help the knife stay sharper for longer. Use on hard surfaces like plates and bamboo will reduce the edge life and can result in edge damage. Special attention needs to be taken to prevent edge damage. Scraping, twisting and forceful as well as using on hard or very dense foods can result in chipping.

We recommend hand sharpening on whetstones. We have found that most Japanese knives perform best at a finer finish starting around 4000. Avoid pull through sharpeners and non-water cooled mechanized sharpening. Ceramic honing rods are preferred.
