Cutlery Day (Hamono no Hi) — November 8th "Good Blade" Wordplay

What Is Blade Day?

Blade Day (Hamono no Hi) is a day to give thanks to blades such as kitchen knives, scissors, and knives, and to rethink how to use and care for them properly. It was proposed by the Gifu Prefecture Seki Cutlery Industry Federation in Seki, Gifu. According to the Japan Anniversary Association, its founders include the city of Seki and the Seki cutlery federation, along with cutlery groups from Sanjo (Niigata), Echizen (Fukui), Tokyo, Kyoto, Kami City (formerly Tosa-Yamada, Kochi), Yoshida in Unnan City (Shimane), and Sakai (Osaka). It is said to have been registered in 1996. Blades are tools of daily Japanese life long refined by smithing skill. They are used almost every day, which is exactly why their sharpness and safety are easy to overlook. The day is also a chance to look at the history and skills of those production areas.

A Wordplay and the "Fuigo Festival"

The date has two origins. One is a pun: "i-i-ha" (1-1-8) sounds like "ii ha," a good blade. The other is the "Fuigo Matsuri," held across Japan on the eighth day of the old eleventh month by craftsmen who use bellows, such as metal casters, blacksmiths, and stonemasons. A fuigo is a bellows that blows air into a fire to raise the furnace temperature, and it is essential for making blades. The cutlery towns tied their anniversary to the day craftsmen thank their tools and fire.

• Seki's climate:Swordsmithing in Seki is said to have more than 700 years of history. According to the city, easy access to pine charcoal for the forges, good clay for hardening blades, fine water, and boat transport on the Nagara and Tsubo rivers made it an ideal place for swordsmiths
• Kamakura period:Tradition says the swordsmith Motoshige came to Seki from Hoki Province in 1229 and began forging swords there; his son Kaneshige, who studied under Masamune, is credited with greatly developing the Seki school
• Muromachi period:The number of swordsmiths is said to have passed 300, and Seki blades became known as "unbreaking, unbending, and sharp." Kanemoto II, famed as "Seki no Magoroku," made sturdy swords with a distinctive method called "shiho-zume," and his "three cedars" blade pattern became famous. Warlords prized Seki swords, making it a sword center on a par with Bizen
• Today:Seki is one of the "three great cutlery centers of the world" along with Solingen in Germany and Sheffield in England, and it is the birthplace of the razor maker Feather. The Seki Cutlery Festival, running since 1968, is held each October (its 58th in 2025), with a large blade sale by local makers and wholesalers and demonstrations of traditional sword forging

Blade Memorial Services and Basic Care

At the Seki Traditional Swordsmith Museum grounds stands a "blade mound," where a memorial service is held for blades that can no longer be used, a culture of thanking tools even after their working life. For kitchen knives at home, the basics are to wash them right after use and wipe off the water, since leftover moisture causes rust. A dull blade makes you use extra force and loses control, which is actually more dangerous. Sharpening on a whetstone restores the edge and is also gentler on food.

Tips for Marking This Day

• Think about how sharp your knives and scissors at home are, and check for rust or chips. If a blade has gone dull, consider sharpening it or having it professionally re-sharpened
• Snap off the used segment of the blade in your office cutter knife, and get into the habit of retracting the blade after use
• Store kitchen knives in a stand or sheath so the edge is never exposed, and keep them out of children's reach
• Dispose of blades you can no longer use according to your local rules, in a way that is safe

A Day to Thank Your Tools

Blade Day is a day to notice how much we rely on everyday tools. A blade that will not regain its edge however often it is sharpened, a loose handle, or spreading rust are all signs that it may be time to replace it. Think about the history of the cutlery towns and take another look at the blades you use every day. The Seki festival also features knife sharpening and a blade-knowledge test.
