Muneishi Petty Aogami #2 Kuro-uchi 120mm (4.7")
- Knife Care
Muneishi Petty Aogami #2 Kuro-uchi 120mm is a small Japanese kitchen knife that comes in handy when a larger knife is a bit unpractical. This refers to all the delicate tasks, such as mincing, peeling or paring, where the shorter blade can be used in-hand comfortably.
The knife’s steel and looks are kept pretty closely within tradition. High-carbon Aogami #2 steel is easy to sharpen to a very fine sharpness and also has slightly improved corrosion resistance in comparison to other traditional steels. A magnolia handle which is traditionally used was swapped for a beautiful cherry wood oval piece with a pakka ferrule – providing a nice contrast to the dark look of the blade.
Petty knives are intended for all those smaller tasks where larger knives are deemed unwieldy. On and off the cutting board. A must-have knife in every kitchen, it can be used for peeling, mincing, paring and decorating food.
Aogami #2 steel is a very popular steel in Japanese knifemaking and one of the finest high-carbon steels, meaning the knives forged from it will have excellent edge retention and also sharpen very easily. At the same time, it is less resistant to corrosion, meaning the blade can develop a patina, while longer exposure to water or other corrosives could also lead to rusting. This is improved to some extent with the addition of chromium and tungsten, but it’s still a high-carbon steel that should be maintained accordingly. Aogami #2 steel is composed of carbon (C) 1.1%, chromium (Cr) 0.5%, manganese (Mn) 0.3%, and tungsten (W) 1.5%.
High-carbon steels are hard, but brittle for the same reason, which makes them more prone to breakage and chipping. To prevent that, blacksmiths sandwich the blade’s core, made from Aogami #2 steel, between multiple layers of softer, more corrosion resistant steels. This improves the blade’s flexibility—and most importantly with high-carbon steels—protection from corrosion and rusting too.
It has a double bevel (symmetrical) blade.
Kuro-uchi finish, the unprocessed (black) part on the top side of the blade has already developed a dark patina, which protects the blade and gives it a traditional Japanese look. The knife bears barely visible impressions of the hand-forging process (round hammer dents on the blade), which gives it a beautiful rustic finish. Kanji "made by Muneishi" 宗石作 has been hand-chiseled onto the blade.
Octagonal Japanese (Wa) handle made out of cherry wood is suitable for right- and left-handed individuals.
ABOUT THE BLACKSMITH:
Muneishi smithy was founded in 1955. Hirotaka Muneishi, the second-generation knife smith, is renowned for manufacturing forestry knives such as axes and machetes for the local woodsmen. Kosuke Muneishi, the third-generation blacksmith and now the head of the company, has since branched out to making kitchen knives. He mostly uses Aogami Super steel and performs all the steps himself: tempering, forging, hammering and edging knives. His knives have very nice grinds, good profile, and are very affordable.

Blade wear depends on the quality of steel, usage and maintenance of the blade. Japanese knives are made of high-quality steels. Follow these tips to keep your Japanese knife in top-notch shape:
✔ Use a wooden, plastic or rubber cutting board.
✔ After use, wash the knives and wipe them dry.
✔ Use a magnetic rack, knife blocks, or use protective knife sheath (saya).
✔ A good cutting technique is your best bet to prolong sharpness.
✔ Use sharpening stones to sharpen the knife.
