The smith lifts the steel from the charcoal and it glows almost white. A hammer comes down, then another, in a rhythm that hasn't changed much in centuries. Sparks scatter across the dirt floor.
This is Seki, a small city in Gifu Prefecture whose blade-making tradition, begun by swordsmiths, goes back about 700 years. Today the city's modern knife industry is known worldwide, and Seki is roughly an hour or more from Nagoya, depending on route and connections.

What tamahagane is, and isn't
Yamato-tradition smiths settled in Seki in the 14th century for its forests, clean water and fine clay.
Tamahagane is steel smelted from iron sand in a clay tatara furnace over about three days, mostly in Shimane Prefecture. Folding the steel, orikaeshi-tanren (repeated folding and hammering), comes later and helps even out carbon and drive out impurities. A third, separate stage is kobuse (a laminated build), which wraps a hard outer steel around a softer core. Casual accounts often blur all three into one.
Here's what surprises many visitors: modern Seki kitchen knives aren't made from tamahagane. Many use contemporary steels such as VG-10 or carbon steels like shirogami and aogami, though materials vary by maker. Tamahagane belongs to the sword-forging tradition.
The grinding room
The forge is dramatic, but quality is decided in the grinding room, working through whetstones from coarse to fine. The tiny finger-sized polishing stones you may read about belong to sword polishers, not kitchen-knife sharpeners; the two are traditionally separate crafts.
At the Seki Sword Tradition Museum, you can watch sword-forging demonstrations on set days and try sharpening yourself. You'll learn quickly that holding a steady angle takes patience, not strength. (The museum is closed for renovation until March 31, 2027.)
If you buy a knife, think about upkeep. Carbon steels such as shirogami and aogami take a keen edge but rust readily, so they need wiping dry right after use and a light oiling before storage. Stainless is the lower-maintenance choice for a traveling cook.
Know before you go
Demonstration days: The museum is closed for renovation until March 31, 2027. After it reopens, traditional sword-forging demos run roughly once a month; dates can change around festivals and year-end. Check the current schedule before you go.
Cutlery Festival: Every October, with street stalls, sharpening services and factory sales. It's one of the city's busiest weekends, so book transport and lodging early; confirm this year's dates.
Carbon steel rusts: Shirogami and aogami knives rust readily. Dry immediately after use and oil lightly before storage. Choose stainless for less upkeep.
Flying home: Blades generally must go in checked baggage; final rules depend on your airline, airport security and destination country.
Language: Many workshops run in Japanese.
FAQ
Q: How long has Seki been making blades?
About 700 years as a town tradition, not any single workshop. Yamato-tradition swordsmiths settled in Seki in the 14th century; sword-forging continues today, and the city's modern knife industry grew out of that heritage.
Q: What is tamahagane?
Tamahagane is Japanese sword steel smelted from iron sand and charcoal in a clay tatara furnace for about three days. Most tamahagane is made in Shimane Prefecture.
Q: Are Seki knives made from tamahagane?
No. Many modern Seki kitchen knives use contemporary steels such as VG-10, or carbon steels like shirogami and aogami; materials vary by maker. Tamahagane is reserved for traditional swords.
Q: Why are Japanese blades folded?
Folding, or orikaeshi-tanren, evens out carbon through the steel and drives out slag and impurities. It doesn't create tamahagane, which is smelted beforehand in a tatara furnace. Many Japanese swords also use kobuse construction, wrapping a hard outer steel around a softer core. Ten folds produce over a thousand layers.
Q: How do I get to Seki from Nagoya?
Take the Meitetsu line and Nagaragawa Railway, or a bus from Gifu. Allow roughly an hour or more depending on route and connections, and check current timetables.
Q: Can I take a Seki knife home on the plane?
Blades generally must go in checked baggage, not carry-on. Final rules depend on your airline, airport security and destination country.
Q: Can I visit a working knife maker in Seki?
Sometimes, by arrangement. Many Seki workshops are small, run in Japanese, and open to visitors only on request. Our team in Japan can help arrange a workshop visit with an interpreter and a private transfer from Nagoya.
Back in the forge, the steel cools from orange to gray. Somewhere in that blade is a town's 700-year tradition, and a smith who will be back at the anvil tomorrow morning.
