Masakage Stainless Clad Blue #2 Petty Knife 120mm Koishi

Masakage – Koishi Petty 120mm

Petty – Precision Utility

The petty is the small utility knife in a Japanese line-up — designed for detail work, trimming, peeling and in-hand tasks.

At 120mm, this is a true precision tool. Light (just 62g), nimble and thin behind the edge, it excels at shallots, garlic, herbs and smaller fruit or proteins where control matters more than power.

It’s the knife you reach for constantly — not dramatic, just indispensable.

Stainless Clad Blue #2 – Focused Carbon Performance

This blade is constructed in san mai: a Blue #2 (Aogami #2) carbon steel core clad in stainless steel.

Blue #2 is a refined high-carbon steel known for excellent edge stability, strong sharpness potential and satisfying feedback on stones. Heat treated to approximately 62–63 HRC, it takes a very keen edge while retaining enough toughness for confident daily use.

The stainless cladding protects the blade road, leaving only the exposed edge reactive — expect a natural patina to develop over time.

Koishi Finish – Tsuchime Kurouchi

“Koishi” translates to “pebble,” referencing the deeply textured tsuchime (hammered) pattern across the blade face.

Combined with the dark kurouchi (blacksmith) finish, it creates a rugged, forged aesthetic while subtly reducing surface drag during cutting. Functional texture, not ornament.

Masakage – Echizen Craft

Masakage knives are produced in Echizen by skilled blacksmiths and sharpeners working within a long-established craft tradition. Known for expressive finishes and performance-focused geometry, the range blends strong cutting ability with distinctive character.

Thin grinds, consistent heat treatment and attention to detail define the line.

Handle – Octagonal American Cherry

Fitted with an octagonal American cherry wa handle and black pakka wood ferrule. Lightweight, balanced and comfortable in a pinch grip, it complements the blade’s nimble feel.

Steel Care

• Hand wash only — never dishwasher.
• Dry thoroughly after use.
• Use wooden or rubber boards to protect the edge.
• Store safely in a block, on a magnetic rack, or in a saya.
• Strop regularly; sharpen on whetstones when required.
• The exposed carbon edge will develop a patina — this is normal and protective.
