Isamitsu Knives – A New Generation of Japanese Craftsmanship

Isamitsu is a rising Japanese knife maker established in 2022 in Ibaraki, Japan. Led by Yuki Abe—who trained for over a decade under master Teruyasu Fujiwara—the brand reflects a new wave of blacksmithing that blends traditional craftsmanship with a modern, performance-focused philosophy.
Produced in small batches by a skilled and dedicated team, each knife is crafted in-house—from forging and heat treatment through to grinding and finishing. This hands-on approach ensures a high level of consistency and attention to detail that is rare for such a young workshop.

Isamitsu places strong emphasis on heat treatment and blade geometry. Using high-performance carbon steels such as Shirogami and Aogami Super, their knives offer excellent edge retention, a fine grain structure, and outstanding sharpness. The blades are ground thin behind the edge, delivering a smooth, precise cutting experience while retaining enough durability for professional use.

Aesthetically, Isamitsu knives strike a balance between rustic character and refined finishing, often featuring kurouchi or lightly textured finishes paired with well-crafted handles.

White #1 Steel (Shirogami #1) – Ultimate Purity, Exceptional Sharpness

White #1 steel, also known as Shirogami #1, is one of the purest traditional carbon steels used in Japanese kitchen knives. Produced by Hitachi Metals, it is highly regarded for its minimal alloy content and extremely fine grain structure.
With a higher carbon content than White #2, White #1 can achieve greater hardness, allowing it to take an exceptionally keen and refined edge. This makes it a favourite among professional chefs and sharpening enthusiasts who value precision and ultimate cutting performance.
White #1 is also incredibly responsive on sharpening stones, offering excellent feedback and ease of sharpening. It allows users to achieve a razor-sharp edge with relatively little effort, making it especially rewarding for those who enjoy maintaining their knives.
As a fully reactive carbon steel, White #1 will develop a natural patina over time and requires proper care, including drying after use and regular maintenance to prevent rust.
