Kobayashi-san crafts these knives using premium SG2 powdered metallurgy steel—an advanced stainless steel prized for its exceptional edge retention, toughness, and ability to take an ultra-refined edge. We’re big fans of SG2, and it’s easy to see why: this high-performance steel offers the durability of a workhorse with the precision of a scalpel.
The SG2 core is clad in a softer stainless jigane, which not only protects the cutting edge but also simplifies sharpening. A finely executed hairline finish on the cladding creates an elegant visual contrast with the polished core steel, showcasing the craftsmanship and attention to detail.
These are true laser-style Japanese kitchen knives—ultra-thin, remarkably light, and incredibly nimble on the cutting board. The balance is spot on, aided by a beautifully shaped octagonal rosewood handle that feels secure and natural in hand. Whether you're slicing vegetables or prepping proteins, this knife delivers precision, speed, and refinement in every cut.Maker: Kobayashi san
