Kuro-uchi Santoku Funayuki 155mm (6.1") blade paired with our SharpEdge stabwood handles.
Santoku Funayuki is a jack-of-all-trades in the kitchen and will excel at all types of chopping and slicing on the kitchen board; you might find it a touch short only for very large chunks of meat.
We chose a universal, octagonal shape that comfortably fits the hands of both right- and left-hand users. It offers a firm grip for easy and comfortable use.
Handles are made of natural maple wood, which undergoes a special procedure of stabilization with resin. This ensures a long service life of the handle. During this process of stabilization, a color pigment is added which penetrates the wood in different ways, creating unique patterns. This makes every handle one-of-a-kind.
Compared to the basic Santoku knife shape, the spine of funayuki’s blade tapers towards the tip, creating a slight curve between the tip and the midsection. The standard shape of a santoku knife featuring a straight edge with a narrow sheep’s foot blade thus transforms into a blade that looks like a deba but is better suited to precision cutting, where you need really thin cuts (this makes it unsuitable for cutting through bones or making more robust cuts). As opposed to a forward and backward motion slicing technique that is characteristic of santoku knives, the curved belly requires a rocking back and forth motion. A pronounced tip and triangle design are perfect for cutting smaller pieces of meat and for filleting fish.
The word funayuki means “the boat (ocean) goes” and the knife was originally used on fishing boats, primarily as a lightweight fillet knife to test the quality of the catch, as well as to prepare meals at sea and perform a range of cleaning and prep jobs.
In short: funayuki blade is a superb hybrid between various traditional shapes of Japanese knives, such as gyuto, santoku and deba, which makes it a versatile, all-around knife for various tasks in the kitchen.
Yoshida Kuro-uchi series knives are traditional Japanese rustic knives. Its price is very affordable for the quality of a hand-forged knife. It is suitable for the first purchase of a traditional Japanese knife. The blade is forged in SUJ-2 steel, which offers incredible capacities, hardness is 63-64 HRC, and at the same time the knife is very easy to resharpen. The blade needs some extra care. After the use rinse it well and dry it. The name of kuro-uchi refers to the final look of the blade, which is unprocessed on the top and has already developed dark patina, which protects the blade.

☝️ 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.
☝️ THIS KNIFE MAY DEVELOP PATINA
Knives made of traditional Japanese 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.
GENERAL KNIFE CARE TIPS:
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.
❗️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.
