The petty knife is the Japanese take on the classic paring knife – versatile and precise with a slim, pointed blade and a slightly wider profile than the European equivalent. Japanese knives are also significantly thinner and sharper than typical Western stainless-steel blades, making them ideal for delicate, detailed work like slicing fish, fine herbs and perfectly ripe tomatoes without crushing.
Western knives, often made from softer stainless steel, are less prone to chipping but dull much more quickly and will eventually need to be professionally sharpened to restore their edge.
This knife features a double-bevel edge, sharpened on both sides of the blade to deliver clean, accurate cuts with minimal effort.
Hand-sharpened by master craftsman Tahara Shunichi in Sakai, Osaka, a city famed for its blades, this knife is made from white steel, a pure steel prized for its hardness and sharpness. It is made by combining iron with carbon without adding other compounds. With a Rockwell hardness of HRC 64–65, it holds an extremely fine edge, perfect for slicing without tearing or crushing.

Japanese knives require a little bit more maintenance than Western knives as white steel can rust if not dried properly, the reward is a blade that holds a razor-sharp edge far longer. With minimal effort, you can keep these knives in top condition yourself, without the need for regular professional sharpening.
To maintain your blade:
- Dry thoroughly after each use to avoid moisture buildup.
- Sharpen regularly using a water whetstone (available here) to preserve the edge and prolong the life of the knife.
- Avoid using a honing rod, which can damage the fine edge of Japanese blades.
With the right care, these blades will remain sharp and precise for years to come.
