Kei Kobayashi R2/SG2 150mm Petty with Morado Handle

by Kei Kobayashi


This Petty is handcrafted by Kei Kobayashi with R2/SG2 steel core, clad in stainless steel and heat-treated to 63 HRC. The blade has superb grinds that are exceedingly smooth, with a laser distal tapering. The knife is sturdy and the cutting is authoritative. The incredibly smoothly polished blade is paired with a beautifully crafted octagonal handle made of Morado wood with a white Pakka wood Kuchiwa. High-quality fit and finish can be seen all over this knife, including the beautifully polished handle, the precise mounting, as well as fluidly polished choil and spine. It's one of the most polished knives at this price point.

About Kei Kobayashi 小林 圭 / Kobayashi Hocho 小林包丁

Kei Kobayashi (小林 圭) is a relatively young knifemaker based in Seki City of Japan, whose knives are truly extraordinary when it comes to fit and finish. Born in 1977, Kobayashi started out as a knife sharpener, sharpening and finishing knives for a couple of top artisans in Seki City. He later founded his Kobayashi Hocho (小林包丁) with his father, and quickly became known for the extraordinary craftsmanship. His knives are true lasers, and he uses only R2/SG2 steel to make his knives. His attention to detail and extensive grinding and sharpening experiences can be seen on every knife he crafted.


Wash and dry with a soft sponge, and safely store after use. Avoid cutting into bones, frozen foods, hard fruit pits.

Cutting Surface:

Recommended cutting surface: wood, rubberized boards and high-end composites, and quality plastics such as polyethene make acceptable cutting surfaces, and will help protect and prolong knife’s edge. AVOID glass, metal, countertops, and other rigid, non-forgiving surfaces.


We recommend sharpening all quality Japanese knives on whetstones, as we believe they yield the best results for your knives.
