Kanjo comes from a family of master sharpeners and has built a reputation for working with advanced steels like HAP40 and ZDP-189, materials only a handful of Japanese makers handle with confidence. The blade is forged from Hitachi's HAP40, a powder high-speed steel known for exceptional hardness and outstanding edge retention, ground into a hamaguri-ba, or clam shell, convex profile that cuts smoothly while staying strong against chipping. At 150mm, this petty knife is the ideal size for fine dicing, mincing, peeling, and other small or off-board tasks where a full-size chef's knife is too much. It comes fitted with a gray octagonal handle made from reinforced laminated wood, giving it a comfortable, secure grip with a clean, modern look. \u003cbr\u003e \u003cbr\u003e\u003cstrong\u003eSpecifications\u003c\/strong\u003e \u003cbr\u003eBlacksmith: Kanjo Tsukahara \u003cbr\u003eOrigin: Seki City, Japan \u003cbr\u003eKnife type: Petty \/ utility knife, double bevel \u003cbr\u003eBlade steel: HAP40, powder high-speed semi-stainless steel \u003cbr\u003eHardness: approximately 65 HRC Blade construction: Hamaguri-ba (convex grind) \u003cbr\u003eBlade length: approximately 150mm (5.9\") \u003cbr\u003eTotal length: approximately 272mm (10.7\") \u003cbr\u003eWeight: approximately 77g \u003cbr\u003eHandle: octagonal \u003cbr\u003e \u003cbr\u003e\u003cstrong\u003eCare notes\u003c\/strong\u003e \u003cbr\u003eHAP40 is semi-stainless and may develop a light patina over time, which is normal and does not affect performance. Hand wash and dry the blade immediately after use, and avoid leaving it wet. Not dishwasher safe. Avoid cutting frozen food or bone, and avoid twisting the blade, as the edge is ground thin for sharpness. Use a sharpening stone to maintain the edge.\u003c\/p\u003e","brand":"Kanjo Tsukahara","offers":[{"title":"Default Title","offer_id":47379661029515,"sku":"007194","price":100.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0679\/5332\/8267\/files\/IMG_7076.jpg?v=1781890897","url":"https:\/\/donnaskitchenconsignment.com\/products\/kanjo-tsukahara-hap40-petty-150mm-octagonal-handle-c046","provider":"Donna's Kitchen Consignment LLC","version":"1.0","type":"link"}
