Misuzu Ko-Bunka is a smaller petty knife that will impress with its versatility and sharpness. This knife is super lightweight (weighing only 50g / 1.8 oz), and features a thin profile with a long and straight blade and a prominent front tip.

Ko-Bunka is a smaller version of the Misuzu Bunka 160mm (6.3") so if you guessed that “ko” means small or short, you nailed it. Ko-Bunka, 105mm long, is a love child of the Bunka and Petty knife. It has a characteristic Bunka shape with a pronounced tip that resembles Tanto blades.

The knife excels at tasks that require a small, versatile utility knife and gives you enough knuckle clearance so that you can comfortably chop herbs, mince garlic, prep smaller veggies or even trim meat. By being such an all-rounder smaller knife, Ko-Bunka will take your kitchen by storm and quickly become the star of your kitchen arsenal.

The core is made of SKS93 steel, which is high-carbon steel, so it will need some additional maintenance and care, and it will develop patina. However, the two outer layers in this san-mai clad steel sandwich are made of stainless steel, which will protect the core steel from rusting. Only the very end of the edge is exposed and there you will notice patina. As with all high-carbon steel knives, sharpening them is very easy. Super fine and smooth sharpness can be achieved even with those who are still learning the skill. The straight blade with almost no curvature is easy to sharpen and is a great profile to learn sharpening skills on.

It has a double bevel (symmetrical) blade.

The blade features a kasumi finish on the bottom and was polished on the upper part. The blade and handle are engraved with traditional Japanese bells.

A basic traditional Japanese wooden handle was fitted on Warikomi bunka. The handle is made of magnolia wood with a black plastic ferrule. Magnolia wood is known for its antiseptic properties, but since it is a soft wood with a light color, it will stain easily, therefore we recommend using the knife with clean hands. Its oval shape makes it especially ergonomic and comfortable to use, both for right- and left-handed users.

Misuzu knives are made in a small family-run workshop in Miki, Japan.

☝️ Japanese kitchen knives in our store are handmade from natural materials. Slight variations in color, texture, weight and other dimensions are possible. We try to give a good photographic representation of our products, however computer screen resolution and colors do vary, so products might not look exactly as they are seen on screen.


Knives made of carbon steels can, due to their low chromium (Cr) content, discolor and develop patina. The knife is the most sensitive when it is still new and a patina had not developed yet, but later, patina will protect the blade. These types of knives require a touch more care:

✔ Wipe it regularly with a clean and dry cloth (you can also do this during use).
✔ After use, rinse it with lukewarm water and wipe it dry.
✔ Coat it regularly with knife maintenance oil or plain refined sunflower oil.
✔ Store the knife by wrapping it in paper which will absorb moisture and protect the blade.

A patina is a thin layer that forms on the surface of oxidized steel and protects it from further oxidation. The patina should not be confused with rust. Patina protects the blade, while rust causes corrosion and deterioration of material, so it should be removed (see Rust erasers).

→ For in-depth information about patina, read our dedicated post on patina.


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.
✔ For storage, use a knife holder or a protective knife sheath (saya).
✔ A good cutting technique is your best bet to prolong sharpness.
✔ Use sharpening stones to sharpen the knife.

❗️Don’t leave the knife in the sink. Wash it by hand.
❗️Don’t wash the knife in the dishwasher.
❗️Don’t use the knife on glass, ceramics, marble or steel surfaces.
❗️Don’t scrape the food off the cutting board with the edge of the blade. Use the spine of the knife instead.
❗️Knife is a tool intended for specific use - cutting food. It is not a can opener, screwdriver, trowel, wire cutter, hammer etc.
