Higonokami: How Japan's Most Famous Pocket Knife Came to Be

A knife with nothing unnecessary

At first glance, Higonokami may look surprisingly ordinary. The handle of traditional models is made by bending a sheet of metal, the blade is mounted on a pivot inside, and an extended lever protrudes from the spine. No handle scales fixed with dozens of parts, no spring and, in the classic version, no mechanical blade lock.

This simplicity is precisely its greatest strength. The knife is easy to carry, its construction is easy to understand and, when handled correctly, it can manage many small everyday tasks. Miniature versions are not mere decorations either. They are real functional knives that can be used for opening packages, cutting string, sharpening pencils or other light work corresponding to their size.

Miki: city of blacksmiths and tools

The story of Higonokami begins in the city of Miki in Hyōgo Prefecture. The area had long been connected with the production of forged tools, saws, chisels and knives. At the end of the 19th century, however, Japan was undergoing the major changes of the Meiji period. The old social order disappeared, demand for traditional swords declined and many blacksmiths looked for products useful in modern everyday life.

It was in this environment that a simple folding knife appeared, one that could be produced at an affordable price and sold to the general public. It was not intended for ceremonies or as a symbol of social status. It was meant to cut, to be easy to carry and to serve people in ordinary work.

1894 or 1896?

In the history of Higonokami, two dates may appear. Many articles and encyclopedic sources give 1896as the year of origin. The archive of Nagao Kanekoma itself, however, links the decisive form of the knife and its naming already with the year 1894. According to the maker, the roots of the so-called Hirata knives go back as far as the 1880s.

This is not necessarily a contradiction. Similar traditional products often do not emerge at one single moment. Their predecessors are made first, then the construction is adjusted, naming follows, and only later does the product become widespread enough for its origin to be associated with a specific year.

Chikiri: the little “tail” that changed the whole knife

The most distinctive construction element of Higonokami is chikiri – the extended part of the blade resembling a lever or tail. Chikiri allows the blade to be opened with the thumb. When fully opened, the lever rests against the top of the handle and the user naturally presses it with the thumb during work.

Higonokami therefore belongs among knives known as friction folder. In the open position, the blade is supported by friction in the pivot and by hand pressure on the chikiri. The traditional construction, however, has no classic blade lock. Chikiri must therefore not be confused with a mechanical lock such as a liner lock, back lock or button lock.

How Higonokami got its name

The name is written with the Japanese characters 肥後守 and comes from the expression “Higo no Kami”. Higo was a historical province on the island of Kyushu, corresponding to most of today’s Kumamoto Prefecture. The word “kami” here relates to the historical official title of a provincial administrator or governor.

Loosely, the name may be translated as “administrator of Higo”, “protector of Higo” or the better-known but less precise “lord of Higo”. According to production tradition, Tasaburo Shigematsu chose this name because a significant part of his customers came from the Kumamoto area, the former Higo Province. The distinctive name helped the knife stand out and supported its sales.

Higonokami through time

From school pencil cases to a Japanese icon

Today, the connection between a schoolchild and a sharp pocket knife would seem unusual, but at the beginning of the 20th century Higonokami was a common working tool in Japan. Children used it for sharpening pencils and small craft work. With the knife, they often learned precision, patience and respect for a sharp tool.

Its popularity at the time was linked to affordable price, compactness and easy sharpening. Higonokami was carried by schoolchildren, craftsmen and people who needed a simple knife for everyday activities. Competitions in the neatest and most precise pencil sharpening became a traditional symbol of this era.

Gradual industrialization, however, changed the way people worked and the ordinary equipment of homes and schools. Disposable snap-off knives and electric pencil sharpeners were more convenient, and the traditional pocket knife slowly lost its most common use.

The event that changed the Japanese attitude to knives

Another major turning point came at the turn of the 1950s and 1960s. Campaigns against carrying knives intensified in Japan, and public sentiment was strongly affected by the assassination of politician Inejirō Asanuma in 1960. The attacker was a seventeen-year-old youth.

It is important to add a detail often overlooked: Higonokami was not used in the assassination, but a traditional short sword of the wakizashi type. The tragic event nevertheless increased pressure for regulation of blade carrying and removal of knives from the school environment. Combined with the rise of modern tools, this meant a sharp decline in demand.

Many makers closed down or moved to other products. Of the dozens of workshops, only one company eventually remained authorized to use the original Higonokami trademark – Nagao Kanekoma Factory.

Trademark or generic knife type?

The word Higonokami is commonly used today as a designation for a certain type of Japanese folding knife. From a historical and commercial point of view, however, it is also a protected brand connected with the knifemakers’ association in Miki.

After the manufacturers’ union was established in 1899, the market was flooded with cheap, lower-quality imitations. In 1910 the makers therefore registered the trademark and limited its use to association members. According to Nagao Kanekoma, this family workshop is today the only successor authorized to use the original mark.

The fifth generation of the Nagao family

The Nagao Kanekoma family workshop follows the work of founder Komataro Nagao and more than a century of knifemaking tradition. The company is headed by fifth-generation representative Mitsuo Nagao. Production remains connected with the city of Miki and combines hand-forging methods with preparation of individual metal parts.

Original knives are usually easy to recognize by their simple metal handle, stamped Japanese characters and typical chikiri lever. Handles may be brass, blackened or otherwise surface-treated. Some historical and decorated variants bear motifs of animals, flowers, landscapes or portraits.

The brass handle, however, does not remain the same forever. Through contact with hands, air and use it gradually develops patina. This gives each piece its own appearance and reminds us that the knife is not an anonymous display object, but a tool that ages together with its owner.

Warikomi: hard core between softer layers

Many traditional Higonokami blades use the warikomiconstruction. Hard cutting steel forms the core of the blade and is surrounded on the sides by softer metal. The hard core forms the edge, while the side layers make processing easier and support the overall toughness of the blade.

Not all models, however, need to have the same steel or the same layered construction. The Nagao Kanekoma range includes variants made of SK carbon steel, Aogami or Blue Paper Steel, Shirogami or White Paper Steel, damascus blades and more modern stainless variants.

Beware of a common confusion: Aogami does not mean White Paper Steel. Aogami is blue paper steel, while White Paper Steel is called Shirogami in Japanese.

From bamboo leaf to a tip reminiscent of a katana

The shape of the Higonokami blade has evolved over the years. Older models could have an elongated tip reminiscent of a bamboo leaf. Today, the classic version is often considered to be a blade with a pronounced downward bevel of the spine toward the tip.

There are also variants called Sword, whose tip visually approaches the kissaki profile of a Japanese sword. A traditional Higonokami usually has a double-bevel V-shaped edge, so its use is not limited only to the right or left hand.

Why is Higonokami returning again?

In a world of complex folding knives full of bearings, titanium parts and modern locks, Higonokami feels like a return to the very essence of a cutting tool. Each part has a clear purpose and the principle of the knife can be understood in moments.

Collectors are attracted by its history, handwork and many variants. Practical users appreciate its compactness and the easy maintenance of its simple mechanism. Lovers of Japan see in it an object that connects everyday life with a long craft tradition.

Higonokami also naturally develops a distinctive appearance. Brass darkens, the carbon blade forms patina and the surface gradually records the way it is used. Two originally identical knives can therefore tell completely different stories after a few years.

Safety: tradition does not replace caution

Higonokami is a real sharp knife, even in miniature form. The traditional model has no classic lock, so it is not suitable to rely on the blade staying mechanically locked. During work, the thumb must remain on the chikiri, the cutting motion must be controlled and the blade must not be exposed to pressure that could close it.

• Always cut away from the body and away from your fingers.
• Do not use the knife for prying, chopping, screwing or side loading.
• Close the blade completely before storing.
• Do not treat the miniature model as a toy and do not give it to children.
• Carry the knife responsibly and respect the rules that apply where you use it.

How to care for Higonokami

Carbon blades such as SK, Aogami and Shirogami can corrode when exposed to moisture. After use, clean the blade, dry it immediately and apply a very thin layer of suitable protective oil. If you use the knife for food-related work, choose oil intended for that purpose.

Keep the pivot area clean and lubricate only sparingly. Do not soak the knife, do not wash it in the dishwasher and do not store it long-term in a damp sheath. Patina on a carbon blade or brass handle is natural, but active orange corrosion must be removed.
