Kei Kobayashi — The Sharpener Who Became a Master Maker

Kei Kobayashi (小林圭), born in 1977, is a highly regarded Japanese knife maker based in Seki City, Gifu Prefecture—the historic centre of Japanese blade-making.

His knives are celebrated for precision, elegance, and refinement—ideal tools for cooks who demand both art and performance in the kitchen.

Kobayashi's SG2 Migaki is a lineup that designed purely to pursue cutting performance and usability in the context of a professional kitchen. The combination of low maintenance, highly wear resistant SG2 steel, simple, low friction Migaki finish and a blade geometry that is tuned to glide through all kinds of food, made these knives a ideal choice for professionals and those who expect highest performance from their blades.The highlight of these knives must be the thin blade that Kobayashi san put onto with his masterful sharpening skill, the sub-2mm spine thickness and razor-like thickness behind the edge make these knives the definition of "laser". At the same time, it is one of the smooth cutting laser I've ever tried. The slightly rough Migaki finish and swell-tuned convex geometry produced by Kobayashi san's rich experience have lead to a cuts that are free of sticking, which is uncommon on a thin knife. Also unlike the commonly seen thin blades, Kobayashi's knives have great rigidity.It could be the thicker body created by the convex grind which give more support to the blade against bending, and potentially higher hardness from heat treatment. This thin and solid blade offer very commanding cuts and would give you confidence in the most challenging tasks that require great precision.Despite the simple design, all the details are finished to a very high level. The shiny spine and choil stands out under the contrast with the Migaki blade surface and speak proudly about the attention to details. As for the steel, SG2 still is one of the best option for knife making in the industry, it is balanced in other aspect and still offer excellent edge retention that can comfortably last through weeks of intense preps.This SG2 line are incredible, especially as professional tools. It respond to the demand of professional kitchen with top notch cutting performance, great edge retention and excellent handling, and didn't add any fancy feature that oriented for aesthetic. Minimalistic and focused, Kobayashi's SG2 Migaki line is build for professional and those who approach their cooking seriously. Read less
