Furaibo 風来坊 - vagabond, wanderer
a person who wanders from place to place without a fixed home: one leading a vagabond life.

Just like a vagabond wanders the earth without rest, seasons flow into each other and bring change on their way. The sun shines and turns to rain, wind blows past us and we weather the storms, nature perpetuating itself. And in the same steady flow, tradition and convention progress slowly and either give way to new ideas and inventions or reinforce the established status quo.

Centuries of Japanese tradition of sword and blade manufacturing have allowed for such natural processes to play out and birthed many iterations of different blade shapes, sizes and materials they forged them from. Japanese kitchen knives serve as a sort of time capsule, preserving this spirit of excellence and tradition, and the blacksmiths, acting as amber around fossilized remnants of history, pass them to the next generations to keep them alive.

With our previous designs and collaborations with Japanese blacksmiths, we focused heavily on multi-purpose knives to fit the needs of the contemporary chef. We felt that the next move should be a step in the opposite direction, focusing instead on the truly quintessential knives that showcase both the masterful craftsmanship and a rich culinary tradition those contemporary knife shapes were later built on.


🚩 Due to its asymmetrical geometry the blade is suitable for right-handed users only.

Furaibo Deba, ever wandering from recipe to recipe, is forged from Shirogami #1 steel, one of the purest and most traditional steels used in Japanese knife manufacturing. The blade’s finish was kept within the confines of the Japanese concept of negative space (ma 間)* and given a sleek polished migaki look, and a kasumi finish on the kireha. Adorned with a hand-chiseled kanji, three symbols, one word – vagabond.

*the Japanese concept of ma or negative space is a philosophy that guides their approach to design, as well as other, everyday things – the core belief being that absence can be just as important as presence.

Deba is a traditional knife a chef uses to prepare a whole fish; anything from cleaning, filleting, portioning fish, removing fins and heads, to chopping through smaller bones. It can also be used for preparing poultry and other meat with smaller bones.

The deba knife is a well-balanced blend of robustness and precision, achieved through two key aspects: its single bevel edge, and its thick and heavy blade.

The thick and heavy blade equips the deba for heavy-duty work that requires force – removing fins, tails, and fish heads, along with breaking down smaller bones. This thickness and weight provide the required force to perform these tasks without compromising the blade's structural integrity.

Shirogami steel (white steel) is extremely pure steel with a high percentage of carbon and no additional ingredients.  Shirogami #1 is one of the purest steels, and consequently one of the easiest to sharpen. Its characteristics make Shirogami popular with traditional Japanese blacksmiths and sushi masters. The advantage of Shirogami #1 is that it has unparalleled sharpness, is easy to grind, and stays sharp for a very long time. It will require a little more attention in maintenance. The blade will acquire a protective patina with use. Therefore, it’s recommended you wipe the blade dry between and after use and oil it regularly.

Ni-mai lamination method is used on single-bevel knives, where a sheet of softer metal is forge-welded onto the shinogi (front) side of the blade’s hard core. This reinforces the blade’s structural integrity and consequently makes it tougher.

It features a single-bevel edge and is therefore suitable for right-handed people only. This asymmetrical edge geometry allows for a more acute angle on one side, resulting in an extremely sharp cutting edge. This single-bevel deba knife can therefore execute cuts with surgical precision and achieve fine, clean slices of food, making precise cuts along bones. This is crucial, as filleting fish can be tricky and requires precise maneuvering, so using a sharp deba is essential in reducing the risk of damaging the delicate fish flesh.

This knife sports a minimalistic migaki finish, meaning the blade has been polished. The kireha, or “blade road” is adorned with a matte kasumi finish that marks the transition between the jigane (softer outer layer of steel) and hagane or the blade’s hard core.

☝️ 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.
