Authentic Japanese Woodworking Tools. Japanese Oire Nomi 18mm approx. 0.71 in – All HSS Blade by Yoshio Usui. This chisel features an All HSS Blade, an Akagashi (Japanese Red Oak) handle, and a single ura back. Oire Nomi is a standard Japanese bench chisel used for general woodworking, joint fitting, trimming, and other everyday joinery work. This example has a blade width of 18mm (approximately 0.71 in). A distinctive feature of this Yoshio Usui HSS series is its relatively slim blade profile compared with many conventional Japanese chisels, helping reduce bulk around the work when clearance matters. The blade itself is made from High-Speed Steel as an All HSS Blade. This gives the chisel a different balance of wear resistance, sharpening behavior, and grinding-heat tolerance from conventional carbon-steel Japanese chisels. Why Choose This Item? Long-lasting cutting performance: HSS has high wear resistance, helping the cutting edge maintain effective cutting performance over extended use compared with many conventional carbon-steel chisels. Relatively slim blade profile: this HSS series is made with a comparatively thin, compact blade profile that can be useful when working around joints and confined areas. Greater resistance to grinding heat: HSS retains hardness at higher temperatures better than conventional carbon steels, making it well suited to controlled coarse shaping with a grinder when necessary. All HSS Blade: the cutting blade itself is High-Speed Steel rather than a conventional carbon-steel cutting layer. Akagashi (Japanese Red Oak) handle with a single ura back. Maker & Brand Information. Maker: Yoshio Usui. Wholesaler Brand / Inscription: Tachibana Toshiaki. BANKANE identifies the maker and wholesaler brand separately so that the name appearing on the chisel is not incorrectly presented as the maker. Steel / Material Information. The blade is made entirely from High-Speed Steel (HSS) as an All HSS Blade. HSS is valued for high wear resistance and for retaining hardness at elevated temperatures. In practical use, this means the edge is well suited to maintaining cutting performance for extended work, while the steel also tolerates the heat generated during controlled grinder shaping better than conventional carbon-steel chisel blades. This does not mean overheating is harmless. Excessive heating of the cutting edge should still be avoided when using a grinder. Because the entire blade is HSS, ordinary synthetic waterstones may remove material very slowly. Diamond stones or high-cutting-power ceramic stones specifically capable of sharpening HSS are recommended. The exact HSS alloy grade, hardness, heat-treatment specification, and detailed manufacturing process have not been confirmed and are therefore not stated.

The cutting edge is already formed. Experienced users may refine the edge according to their preferred sharpening geometry and finish. Only included when shown and stated in the individual listing. Please refer to the photographs provided in the listing. Protective lacquer, normal finishing marks, and natural variations in the Akagashi handle may be visible. BANKANE avoids unnecessary polishing or modification and keeps the tool as close as practical to its supplied condition. Please review all photographs carefully. The photographs and listing details form an important part of the description. The chisel is supplied with a cutting edge already formed. Users may use the supplied edge after normal inspection or refine it according to their preferred finish and geometry. Sharpening an All HSS Blade: HSS is considerably more wear resistant than conventional carbon-steel chisel blades. Ordinary synthetic waterstones may therefore remove material very slowly. Diamond stones or high-cutting-power ceramic stones capable of sharpening High-Speed Steel are recommended when significant material removal is required. HSS retains hardness at higher temperatures better than conventional carbon steels, providing greater tolerance for heat generated during controlled grinder shaping. Excessive heating of the cutting edge should still be avoided. After use, remove wood residue and moisture. Keep the blade clean and dry, and apply suitable rust protection when necessary, especially during long-term storage. For sharpening, use abrasives with sufficient cutting ability for HSS, such as diamond stones or suitable high-performance ceramic stones. Important Notes for Use. The relatively slim blade profile is an intentional characteristic of this HSS chisel series. HSS provides high wear resistance and helps maintain cutting performance over extended use. Use sharpening media capable of effectively grinding HSS. HSS has greater resistance to grinding heat than conventional carbon-steel blades, but excessive overheating should still be avoided. The exact HSS alloy grade and hardness are not stated because they have not been confirmed. Why We Describe Our Tools This Way. Japanese woodworking tools are traditionally prepared and adjusted by the craftsman before use. Rather than describing every unused tool as “ready to use, ” BANKANE explains its actual condition and any preparation that may still be required. We describe confirmed information in detail and avoid presenting uncertain claims as established fact. Our goal is to give buyers enough accurate information to decide whether the tool is suitable for their work, collection, experience, and preferred method of setup. BANKANE offers authentic Japanese woodworking tools sourced in Japan. We describe each item as clearly and honestly as possible, including storage marks, oxidation, wear, packaging condition, and any sharpening, fitting, or adjustment that may be required. The photographs and individual listing details are provided to help buyers understand what they are purchasing. We believe that honest descriptions and accurate photographs are just as important as the quality of the tools themselves. Photographs and Included Items. Only the items shown in the photographs and specifically stated in this description are included. Rulers, measuring tools, display stands, background materials, and other photography accessories are not included unless specifically stated. Colors and surface appearance may vary slightly depending on lighting, photography, and display settings. For listings with more than one unit in stock, the item received will match the stated maker, model, size, and specification, but wood grain, forged patterns, color, markings, or other individual details may vary. When the exact photographed item will be supplied, this will be stated in the individual listing. Preparation of Traditional Japanese Tools. Traditional Japanese woodworking tools are commonly supplied with the expectation that the user will perform final preparation, sharpening, fitting, and adjustment. Unless this listing specifically states that the tool is ready to use, the blade may require sharpening or fitting. A Japanese hand plane may also require adjustment of the wooden body, blade bed, blade mortise, mouth, sole, and chipbreaker before use. Natural wood can expand, contract, twist, or move because of changes in temperature and humidity during storage and international transportation. Final adjustment should therefore be performed after the tool has acclimated to the environment where it will be used. Measurements and weight are approximate and may vary slightly depending on the measuring method. Please allow for a small margin of error. The item will be visually inspected again before dispatch. The item will be packed carefully using appropriate protective materials for international transportation. Important Information for U. Please review the final amount shown at checkout and check the current import rules that apply in your destination country before purchasing. Thank you for visiting BANKANE Carpenter’s Shop.
