Japanese tradition.
Modern precision.

Osantoku knives are forged around a VG-10 steel core hardened to 60–61 HRC, then sharpened by hand to a 15° edge. That means they're dramatically sharper, hold their edge far longer, and are balanced for control — unlike soft, stamped supermarket knives.

VG-10 is a premium Japanese stainless steel prized for its hardness, edge retention and corrosion resistance. It lets the blade stay razor-sharp through months of daily cooking while resisting rust and staining.

Not at all. Hand-wash and dry it after use, hone occasionally, and sharpen on a whetstone a couple of times a year. Treated well, it will outlast everything else in your kitchen.

It's an all-purpose bunka/kiritsuke profile — perfect for vegetables, herbs, fish, boneless meats and precise slicing. Avoid bones and frozen foods to protect the fine edge.

Yes. The octagonal American walnut handle is sealed and shaped for a secure, comfortable grip. A light wipe of food-safe oil now and then keeps it looking new for decades.

Every Osantoku is backed for a full 365 days. If your knife fails due to a craftsmanship or material defect within the year, we'll repair or replace it free — and we include free re-sharpening guidance to keep it performing for years to come.

Cook with your knife for 30 days. If it's not the best knife you've ever used, send it back for a full refund — no questions asked.
