Honkyuichi Petty 120mm Shirogami no. 2

Honkyuichi Petty – Shirogami No. 2 (120mm)

Product description

This Japanese Petty-type kitchen knife with a blade length of approximately 120 mm comes from the traditional Honkyuichi Hamono blacksmith workshop, which dates back to the Edo period. Production takes place in Shimabara, Nagasaki Prefecture, where the fourth and fifth generations of masters continue the legacy of blacksmith Kyuichi and maintain classic hand-made techniques.

The blade is made of Shirogami No. 2 (White Steel) carbon steel, which is highly valued for its exceptionally fine edge, high sharpness and very easy sharpening. The steel is traditionally hardened, including using spring water from the Shimabara region, which contributes to balanced properties and stable cutting behavior.

The blade construction uses a soft iron sheath, which increases toughness and makes maintenance easier. The Petty type is a smaller all-purpose knife , ideal for precision work, slicing fruit, vegetables, herbs or smaller tasks in the preparation of ingredients. Thanks to its compact dimensions and low weight, it offers very good control and precision.

The handle is made of magnolia wood (Ho wood) , which is light, pleasant to the hand and traditionally used in Japanese working knives. The plastic mouth protects the joint between the blade and the handle from moisture. The overall balance of the knife supports comfortable work even during prolonged use.
