The 120mm petty is the compact sibling in the Mizu petty range, sized for in-hand peeling, trimming, and detail work where even 150mm would be more knife than needed. Ikeda-san hammer forges this at Takefu Village in Echizen in the same fully reactive iron-clad san mai construction that defines the Mizu line throughout.
The Blue #2 carbon steel core is hardened to 62-64 HRC and wrapped in soft reactive iron, finished in a kurouchi, or black as-forged, surface. At 121mm blade length and 30mm tall it is an easy, precise knife to control for small tasks, and the reactive iron cladding means the whole blade develops a protective patina with use rather than just the cutting edge. The cherry oval handle with marbleized plastic ferrule is the same practical, traditional fit found across the Mizu line.
Care Instructions: The Mizu line uses a fully reactive iron cladding over the Blue #2 core, so the entire blade face develops a patina with use, not just the edge. Wipe and dry the blade immediately after use, avoid leaving acidic foods against the blade, and apply a light coat of camellia oil for longer term storage. Hand wash only.
