    The History of Japanese Knives

    The earliest artifacts of Japanese knives can be traced back to the Nara Era (710-794), which are displayed at the Shosoin (正倉院; the Imperial Treasure House) in Nara prefecture. The blade and handles were long and narrow, 40cm in length and 2cm in width with a slight curve. It is said that this type of knives was used by the aristocracy for religious ceremonies. Called Hocho-shiki (包丁式; literally “knife ceremony”), the knives were used to break down carps and cranes to the tune of music.

    Unlike swords, which were considered family heirlooms and passed down generations, knives were everyday tools that with daily use, would disintegrate over time. Therefore, while there are no surviving artifacts of knives, there are plenty of written records, scroll paintings and drawings of knives.

    Evolution Beyond Samurai Swords

    When we speak of Japanese knives, it cannot be forgotten that it was greatly influenced by the technological development of Japanese swords. These swords called Katana (刀) were reserved only for the Samurai (武士), a military nobility serving a feudal lord. The creation of this class, followed by the demand for swords greatly boosted the production and development of blade technology.

    During the tumulus feudal unrest of the Sengoku Era (1454-1573), the main sword production regions were located in Okayama, Kanagawa, Kyoto, Nara, and Gifu prefectures. Not coincidentally, the feudal warlords were the strongest in these five regions.

    However, the demand decreased during the Edo Period (1603-1868), an era marked by relative peace and isolationism from the outside world. With the lack of warfare and battles (and therefore, civilians being able to live a non-combative lifestyle), demand for kitchen knives and farming tools such as ax, saws, hatchets increased.

    The creation and possession of weapons, including Katana, were completely banned during the Meiji Restoration of 1868. Called the Sword Abolishment Edict (廃刀令), violators walking around with their swords would have them confiscated by the police. This law, in turn, created unemployment for the sword-smiths and artisans.  

    To withstand the change of time, many of these artisans switched from producing swords to the kitchen and household blades. Some started creating superior products by applying their centuries-old knowledge of sword-making.  A well-known example is Sakai (堺), in Osaka. The area of Sakai had been producing blades from the Heian Era (794–1185) and was famous for their guns, swords, and tobacco cutting knives from the Muromachi Era (1336-1573). To this day, the Sakai area still produces high-quality Japanese knives and their products are highly respected by chefs worldwide.

    Difference between Japanese and Western Knives

    Material

    Japanese knives are traditionally made with a type of carbon steel called Hagane (鋼). The blades are forged in multiple layers, with a brittle carbon steel core and a softer iron steel outer layer. This combination results in an extremely sharp edge, similar to a Japanese sword. Hagane is not as hard as stainless steel and can chip from tough fish bones and rust from residual bits of food or droplets of water on the blade. Thus, professional chefs rigorously maintain their knives to avoid dull and rust.

    Western knives and Japanese knives for household use are made of stainless steel, which is much easier to maintain and durable. They are rust and corrosion resistant, and suitable for those who like to forgo the frequent maintenance of a Hagane knife. Note that stainless steel knives are not inferior to Hagane, it has the perks of retaining its sharp edge and is easier to sharpen.

    Bevel

    Traditional Japanese knives are characterized by its single-bevel blade, a sharpened edge on one side of the blade surface and the other side completely straight. This edge makes it ideal for precise slicing motions; picture the Samurai action scene where he cuts down his foes in an up to down diagonal motion. When sharpening the blade, you sharpen just the one side. However, single-beveled knives are made for right-handed users, so lefties need specialty leftie knife, which can be expensive.

    Western knives, on the other hand, are double-beveled. Most double-beveled blades have a V-shaped blade edge. While not made for high precision cuts, it’s much easier to sharpen.

    Varieties of Japanese Knives

    The realm of Japanese knives are expansive, but not to worry! The everyday Japanese cook will have one or two of the basic knives, whereas the specific purpose knives are primarily for chefs and professionals. But for those who are curious, here’s a list of Japanese knives you may encounter at a Japanese knife shop.

    Note that there are regional varieties when it comes to knife craftsmanship, Kanto (eastern Japan where Tokyo is located) and Kansai (central Japan where Kyoto and Osaka are located) styles being the main ones.

    The Basic Knives

    1. Nakiri bocho (菜切り包丁)

    For peeling, chopping, and slicing vegetables. The blade is thin, straight and double-beveled. Kanto knives are rectangular, whereas Kansai knives are rounded at the tip. It has a blade length of 240-300mm. It’s easier to sharpen than an Usuba and cheaper.

    2. Usuba bocho (薄刃包丁)

    Similar to a Nakiri, but single-beveled. The blade edge is much thinner than a Nakiri, which makes it excellent for paper-thin slices and decorative cuts. Chefs prefer the Usuba over the Nakiri for its precision, but for beginners, it’s a challenge to sharpen the delicate blade.

    3. Deba bocho (出刃包丁)

    For gutting, descaling, and breaking down fish. It has a chunkier blade to withstand cutting thick fish bones. It comes in 3 sizes, for different sizes of fish. Kodeba (子出刃) has a blade length of 90-120mm, Hondeba (本出刃) is the standard size around 210mm, Miokoshi Deba (身卸し出刃包丁) is 180-270mm in length.

    4. Santoku bocho (三徳包丁)

    Literally “three virtues,” it’s named from being an all-rounder for meat, fish, and vegetables. This versatile knife was created around the Meiji era when western cuisine popularized among the Japanese people and the distinction of western and Japanese cuisine blurred. They’re excellent for chopping and long cutting strokes. Nowadays, most Japanese families forgo the Deba and Usuba for one Santoku knife.

    Specialty Knives

    These knives are primarily owned and used by chefs in their respective fields. For example, a sushi chef will own several Sashimi knives, but not a Menkiri knife.

    5. Yanagiba bocho (柳刃包丁)

    Literally “willow blade,” this knife is for slicing blocks of raw fish for sashimi. It has a long and slim blade and curved at the blade tip. Used primarily in the Kansai region. Also generally referred to as Sashimi-bocho (刺身包丁; “sashimi knife”).

    6. Takohiki bocho (蛸引き包丁)

    Also used for slicing sashimi, but rectangular in shape. Used primarily in the Kanto region. Also generally referred to as Sashimi-bocho (刺身包丁; “sashimi knife”).

    7. Fugu hiki (河豚引き)

    Similar to a Yanagiba, but with a narrower and thinner blade. Used specifically for slicing Fugu (pufferfish).

    8. Honekiri bocho (骨切り包丁) or Hamogiri (鱧切り)

    Use to cut the long and sharp bones of pike conger and fat greenling without cutting through to the skin. It’s heavy and straight-edged for cutting precisely and crushing the bones.

    9. Menkiri bocho (麺切り包丁)

    For cutting udon and soba noodles. Heavy with a straight edge, it looks like a cleaver with the blade extending all the way to the handle.

    10. Unagisaki bocho (鰻裂き庖丁)

    For cutting through the slippery Unagi (freshwater eel), a delicacy eaten during the humid months. There are 5 different styles of Unagisaki knives based on the region and the preparation styles. They are Edo saki (江戸裂き), Nagoya saki (名古屋裂き) Osaka saki (大阪裂き), Kyo saki (京裂き), and Kyushu saki (九州裂き).  The sharp tip is used to pierce through the thick skin, then used to filet the long fish.

    Osaka saki (above) and Kyo saki (below)

    Fun Fact: in Kanto, the eel is cut on its back whereas in Kansai the eel is cut on its stomach. In Nagoya (squeezed in the middle of Kanto and Kansai), unagi may be cut from its back or stomach. The Kanto method of eel preparation is steaming then grilling, whereas in Kansai it is grilled.

    Japan-Born Knives (but not used in Washoku/Japanese Cooking)

    There are also specialty Japan-born knives that have adapted to the westernization/globalization of cooking and thus, are not considered traditional per se, but nonetheless beloved by chefs and home cooks.

    11. Gyuto – Chef’s Knife (牛刀)

    Similar to the western chef’s knife, Gyuto (literally “cow knife”) is an all-purpose knife. These knives range from 210-270mm in length, with a tall heel, curved blade, and pointed tip. The knife is excellent for piercing and for rocking motions, although oftentimes slightly more expensive than a Santoku.

    You can see Gyuto and Santoku are quite similar but when placed next to each other, Sankotu has a shorter tip and it’s more angled.

    12. Garasuki (ガラスキ) and Honesuki (骨すき)

    The Japanese version of a boning knife, it’s perfect to break down poultry as well as red meat. Garasuki and Honesuki both are characterized by its triangular blade, sharp tip, and tough blade. Garasuki is larger in size and heftier than a Honesuki. While the knives are not made for cutting through bones, the nifty blade is best to maneuver around tight spaces.

    What Kind of Knife Should I Buy?

    Now that you’ve learned about the different types and are interested to invest in a Japanese knife, which one should you get?

    First of all, there is no such thing as “the best knife.” Many Just One Cookbook readers have asked Nami for her recommendation, and she recommends the Kikuichi Cutlery brand (often featured in her videos). However, if you wish to purchase a high-quality Japanese knife, I suggest doing research beforehand to find the perfect one for you.

    First, I cannot stress enough the importance of physically handling the knives yourself. Never buy knives online without trying it, regardless of the price. If you’re at a reputable knife shop (Japan or abroad), try holding several different types and brands. The knife shop may direct you to knives based on your interest and price range. If possible, ask if the shop has a carrot or something to test the blade.

    A Quick Guide on Choosing the Right Knife:

    When browsing for knives at a shop, it may be helpful to ask yourself the following questions:

    • Grip: How does the grip feel when you’re holding it? Is it too thick or thin that the tips of your fingers awkwardly bump into each other when gripping the handle or too big that your hands feel lost in it?
    • Weight: Does the blade feel too heavy or too light? Assume that you may be holding the knife for 10-15 minutes, will your hands and arm get tired from the weight? Or do you prefer a knife with some heaviness?
    • Length: Is the blade too long or short? People with smaller hands should use knives with a smaller blade, for instance.
    • Material: Do you prefer a blade made of Hagane or stainless steel? As mentioned above, Hagane requires frequent maintenance whereas stainless steel holds its sharpness and is easier to care for.
    • Craftsmanship: Overall, do you trust the craftsmanship? Cheaper blades are made in China and are mass-produced whereas most Japan made knives are forged by hand.
    • Overall: Do you like the design and look of the knife? Would you want an engraving on the blade? While aesthetics alone will not alter your knife skills, you should pick one that you like!

    An anecdote: When I started culinary school in Tokyo, we were given a set of both Western and Japanese knives (Sakai knives, for those curious). While the knives were of high quality, I found some difficult to use as the blades were huge and the grip was uncomfortable in my small hands (for reference, I have really short fingers and small palms). When I started working in kitchens after graduating, I went to a knife shop and after consulting with the shop owner, was recommended a 22cm stainless steel Santoku knife. Not only did I cut myself less often, but I was also much comfortable wielding the blade and saw a great improvement in my chopping skills. While I do not work in kitchens nowadays, I use this knife daily and am much happier with the experience overall.

    How to Care and Maintain Your Knife

    Following the investment of your knife (or knives), you should also seriously consider its maintenance. While this is understandably difficult for the everyday cook, taking great care of them is critically important for its lifespan. Sharpened knives will naturally dull with use, and depending on the material, may rust. While this may be a pain, treat your knives like musical instruments, which need fine-tuning and check-ups from time to time.

    Never use a knife sharpener (the ones that you drag the blade across). Not only does that whittle down the blade, but the friction can also cause strain. The majority of these knife sharpeners are made for the double-bladed Western knives anyway, and not made for Japanese knives. Same with the honing steel, this is only for Western knives. Contrary to popular belief, this does not sharpen a dull blade, it only aligns a bent out edge. Thus, honing makes sense only if you had already sharpened the blade.

    1. Maintaining Your Knife

    There are a few things you could do to maintain the knife at home.

    1. Use a ceramic rod to align the blade — From time to time, simply slice downwards on both sides of the knife about ten times to “bend” the edge back (double bevel blades only).
    2. Wipe your knives well after washing —  Unless you wish for stubborn rust to overtake your blade, always wipe down your knives after hand washing. Also, in general, you should never wash any knife in the dishwasher. The hot water and harsh chemicals from the dish detergent will damage your knife.
    3. Use the right surface to cut — Your chopping board can also affect your knife’s lifespan. Avoid using fancy boards like granite, glass, or other hard surfaces that can chip away the blade and use wood, plastic, or bamboo boards.

    2. How to Test A Knife’s Sharpness

    Depending on the frequency, you should sharpen your knives periodically. For home cooks, Perfect Edge Cutlery recommends sharpening every 4-6 months.

    To check the sharpness of your knife, do the paper test: hold the corner of a sheet of paper with your other hand, and lightly drag your knife across it. If the cut is smooth without dragging, your knife is sharp. Or you can try slicing a tomato: if you can cut through the skin and flesh without squashing the fruit, your knife is ready to go.

    Remember that a dull knife is more dangerous than a sharp one; a sharp knife requires very little effort to cut whereas a dull knife needs pressure, resulting in a deeper (and more serious) incision than a clean (and oftentimes shallow) cut.

    3. Sharpening your Knife

    Option 1: Bring it to a reputable knife sharpening shop

    Take your knives to a reputable knife shop to have it professionally sharpened and polished. This routine may be bothersome and adds up, but you have the satisfaction knowing that your knives are returned beautifully razor sharp.

    Option 2: Sharpen it yourself

    Buy a whetstone and learn how to sharpen yourself. There are online tutorials on YouTube on how to sharpen your knife, but for beginners, it could be rather nerve-wracking! If you have never done it before, practice on a $5 knife and not your favorite $250 prized knife.

    Look for a knife sharpening workshop or ask an expert friend or family. To sharpen, start with a 100o gritstone. If you wish to fine-tune your blade, polish with a higher grit stone above a 4000 grit, and coat with Camilla oil for protection. You should also buy a rust eraser to remove rust and stubborn stains.

    Where to Buy Japanese Knives

    If you’re visiting Japan, check out Kappabashi (for everything kitchen and restaurant supplies related) in Tokyo, Sennichimae Doguyasuji (similar to Kappabashi) in Osaka, various department stores, or seek direct sellers of knife brands. I hope your journey to your one and only knife a rewarding adventure!
