As a third-generation blacksmith, every step of production remains under one roof, from forging and heat treatment to grinding and finishing, preserving the traditional craftsmanship Sanjo is known for.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp class=\"isSelectedEnd\"\u003e\u003cspan\u003eAt its core is Aogami #1 carbon steel, prized for taking an incredibly fine edge with a crisp, precise cutting feel. The blade is clad in Damascus beneath a dark kurouchi finish, creating subtle contrast and depth while ensuring every knife has its own unique character.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp class=\"isSelectedEnd\"\u003e\u003cspan\u003eTo elevate it even further, we assembled it onto a striking custom mono stabilized wood handle in a rich green tone. Bold yet elegant, the uninterrupted grain gives the handle incredible visual flow, while the vibrant green perfectly complements the blade's darker finish. It's a configuration that immediately stood out to us—modern, distinctive, and unlike anything you'll find from the factory.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp class=\"isSelectedEnd\"\u003e\u003cspan\u003eThis version features a 230mm gyuto profile with a nice heel, giving it more knuckle clearance than a traditional japanese knife. The spine measures 3.8mm above the handle before tapering smoothly toward the tip, delivering an excellent balance of power through dense ingredients while maintaining outstanding precision for finer work. Rounded and polished spine and choil complete the premium feel.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eFrom the hand-forged Aogami #1 core and Damascus kurouchi finish to the custom green stabilized handle assembled in-house, every detail of this knife was chosen to create something truly unique.
