Hailing from world-renown Takefu Knife Village, Takeshi Saji is a third-generation blacksmith in his family. With his new Rainbow Damascus limited edition series, he created knives that are a true work of art and could very well be collector's items. We believe, however, that any knife should be used for its primary function, no matter how good it looks. Regardless whether you keep them behind glass or skillfully wield them in your kitchen, these knives will always be a very attractive masterpiece.

Petty or utility knives are basically a smaller version of gyutos or chef's knives, intended for all those smaller tasks where larger and wider knives are deemed unwieldy. A must-have in every kitchen, this small general-purpose knife is used for peeling and slicing fruit and vegetables, while its compact size and a relatively narrow blade also makes it very nimble and thus perfect for filleting fish, cutting poultry, slicing smaller pieces of dry meats and trimming meat. The blade is 135 mm (6.3") long.

Saji Petty Rainbow Damascus 135mm (5.3") is definitely not just a looker. If you check under the hood, you will find some amazing specs there too. The core of this knife is made of high-carbon Aogami #2 (Blue) steel, tempered to around 62-63 HRC. The core is clad with multiple layers of rust-resistant stainless steel to which brass and copper were added, producing a beautiful, iridescent rainbow Damascus pattern that gives these knives their name.

Aogami #2 ranks among the best Japanese steels because it maintains sharpness for a very long time, whilst it is also very easy to resharpen. Due to relatively high percentage of carbon, however, these knives need to be carefully maintained (wipe it dry after every use and oil the blade) to prevent the development of rust. Because the master smith decided to clad the core into layers of stainless steel, the blade is more resistant and forgiving and will not rust immediately if you forget to oil it (but please don’t). Only the bottom part of the blade, where the core made of Aogami steel is directly exposed, is more sensitive.

The Japanese style (Wa) handle is made of very dense and durable rosewood.

The knife is safely stored in a traditional Japanese wooden box with a burned Saji's trademark kanji characters on the top.

In short, this knife is a great example of usable art!

☝️ 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.
