Once completed, this exact configuration became the only one in existence.\u003c\/p\u003e\n\u003cp\u003eMasuda Hamono has been forging blades since the early Showa era, with three generations of the family carrying on the same tradition. Unlike many modern workshops where production is divided among multiple facilities, forging, heat treatment, grinding, and finishing all remain under the same roof—a level of craftsmanship that continues to define the Sanjo region.\u003c\/p\u003e\n\u003cp\u003eThe blade itself features a core of Aogami #1 carbon steel, renowned for its exceptional edge quality, crisp cutting feel, and straightforward sharpening. It is protected by beautifully layered Damascus cladding beneath a rugged Kurouchi finish, creating a blade that balances traditional character with refined craftsmanship.\u003c\/p\u003e\n\u003cp\u003eFor this build, we wanted something warmer and more elegant than our previous customs. The rich reddish tones of the Red Mango Wood are complemented by shimmering Pearl Epoxy, creating subtle depth that changes with the light. Instead of demanding attention, the handle quietly enhances the knife, giving it an unmistakably premium appearance while allowing the craftsmanship of the blade to remain the focal point.\u003c\/p\u003e\n\u003cp\u003ePerformance is equally impressive. The generous heel height provides excellent knuckle clearance, while the 3.7mm spine offers reassuring stiffness before tapering gracefully toward a precise, responsive tip. Rounded and polished spine and choil ensure the knife feels exceptionally comfortable during long prep sessions.\u003c\/p\u003e\n\u003cp\u003eLike every custom build we assemble in-house, this knife was created only once. There are no extras hidden away, no future production planned, and no way to order another identical piece. It is a singular combination of Masuda's traditional forging and Kakushin's custom assembly—built for the collector or cook who appreciates owning something genuinely unique.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/section\u003e\n\u003c\/div\u003e","brand":"Assembled in Canada 🍁","offers":[{"title":"Default Title","offer_id":51600296116457,"sku":null,"price":1100.0,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0261\/4368\/6711\/files\/MasudaMango.png?v=1785415848","url":"https:\/\/kakushin.ca\/products\/masuda-yoshihide-ao1-custom-mango-damascus-gyuto-230mm","provider":"Kakushin","version":"1.0","type":"link"}
