Yoshimi Kato: The Kato Forge's Third Generation
He came to smithing as an adult, married into one of Echizen's most respected forging families, apprenticed under a master who also trained Yu Kurosaki, and now runs the workshop under his own generation's name. Yoshimi Kato's blades, from SG2 damascus to Aogami Super kurouchi, are some of the most widely respected mid-range hand-forged knives sold in the West. Here is the full picture.
Yoshimi Kato in one paragraph
Yoshimi Kato (加藤義実) is the third-generation head of Kato Uchihamono, the Echizen family forge founded in 1948 as Kanehiro (カネ弘刃物製作所) and renamed in 2018 when he formally took over from second-generation master Hiroshi Kato, his teacher and, per the most detailed published profiles, his father-in-law. Working inside Takefu Knife Village, his workshop forges an unusually wide steel range for a family smithy: SG2 powder-steel damascus, VG-10 damascus, and the celebrated Aogami Super kurouchi line long sold in the West under the old Kanehiro name. He also forges several lines for the curated Masakage brand. Expect clean grinds, versatile middle-of-the-market pricing (most gyutos land around $250 to $450), and the closest thing Echizen offers to one forge covering every steel taste. Supply is small-workshop limited.
Who is Yoshimi Kato?
Yoshimi Kato is a smith, and the brand is his name. Knives marked Yoshimi Kato come out of one workshop: 株式会社カトウ打刃物製作所 (Kato Uchihamono Seisakusho, "Kato Knife Manufacturing"), a family forge operating inside Takefu Knife Village in Echizen City, Fukui Prefecture. There is no licensing, no OEM shell game, and no larger corporation behind the label.
His path to the anvil was unusual. Published profiles describe a man who worked as a construction project manager before joining the Kato family and its forge, beginning his smithing career in 2012 according to the company's own history, at an age when most Echizen smiths already have a decade of forging behind them. He trained under second-generation master Hiroshi Kato (加藤弘) and progressed unusually fast, taking over the smithy's day-to-day forging within about five years and becoming third-generation head when Hiroshi handed over the business in 2018.
Two more names orbit this brand and cause endless confusion at retail. Kanehiro is the forge's old company name (カネ弘刃物製作所), which survives in the West as the label on the workshop's classic Aogami Super line. Echizen Kintaro (越前金太郎) is a brand name Yoshimi uses that honors the forge's founder, Kintaro Kato. All of it, Yoshimi Kato, Kanehiro, and Echizen Kintaro, is the same forge and mostly the same hands.
This page covers Yoshimi Kato the brand: the lines, steels, market standing, and buying guidance. The company itself, its 1948 founding, the Hiroshi Kato era, and the full workshop details are on our maker profile, Kato Uchihamono: From Kanehiro to Today. The two pages are designed to be read together.
The maker behind the name
Kato Uchihamono is one of the anchor workshops of Takefu Knife Village, the cooperative of independent Echizen smiths formalized in 1991. The forge's second-generation head, Hiroshi Kato, was a founding master of the cooperative and served as its chairman from 1994; he is arguably the Village's most consequential teacher, having trained Yu Kurosaki, Kurosaki's brother Makoto, and Yoshimi himself in the Kanehiro workshop.
On the family relationship, the sourcing deserves a note, because it is our job to be straight about it. The most detailed published profiles, including interviews with the workshop, describe Yoshimi as having married into the Kato family, making him Hiroshi's son-in-law; a minority of retail listings loosely call him Hiroshi's son; the Japanese primary sources, including the company's own site and the Village's records, state only that he is the third generation without specifying kinship. We follow the detailed accounts: son-in-law, who joined the family and the forge by marriage.
Hiroshi Kato, born 1941, retired from the business in 2018 and remains one of Echizen's most honored elder smiths; he received a national decoration for his craft career in 2023. The workshop Yoshimi now leads employs a small team of younger craftsmen inside the Village. The full company story, lineage, and contact details are on the maker page: Kato Uchihamono.
History and market position
The forge was founded in May 1948 by Kintaro Kato (加藤金太郎) as Kanehiro Hamono, one of the many small smithies rebuilding Echizen's blade trade after the war. His son Hiroshi took the forge into its defining era: a founding master of Takefu Knife Village in 1991, cooperative chairman from 1994, and the teacher whose workshop became the Village's most productive school. Under the Kanehiro name, the forge's Aogami Super knives became a fixture of Western specialty retail in the 2000s and 2010s, widely treated by enthusiasts as a benchmark for hand-forged performance per dollar.
Yoshimi's arrival rewrote the succession story. With no born heir apprenticed at the forge, the family's son-in-law left a construction career, started forging in 2012, and compressed a traditional apprenticeship into roughly five years under one of Japan's best-regarded teachers. He was effectively running the forging by around 2017, and in April 2018 the handover was formalized with a renaming: Kanehiro Hamono became Kato Uchihamono Seisakusho, the family name replacing the old trade name, with Yoshimi as third-generation representative.
The brand's market position today is distinctive in Echizen: breadth. Where most family forges are known for one steel and one look, the Kato workshop fields powder-steel damascus for the modern stainless buyer, VG-10 damascus for the classic stainless buyer, and Aogami Super kurouchi for the carbon-steel purist, all at prices below the celebrity tier occupied by names like Kurosaki. Add the workshop's role forging several Masakage lines, and this quiet forge touches more of the Western hand-forged market than almost any of its neighbors.
The Yoshimi Kato lines
Like all small-forge "lines," these are recurring steel-and-finish combinations documented across specialty retail rather than a fixed official catalog. Availability rotates. Prices are approximate street prices in USD for single knives as of 2026.
SG2 / R2 Damascus
The modern flagship family: SG2 powder steel cores under damascus cladding, documented at retail in standard, nickel damascus, and black damascus variants. Stainless throughout, exceptional edge retention, and the line that made Yoshimi's own name (as distinct from the Kanehiro legacy) in the West. Gyuto, santoku, bunka, nakiri, kiritsuke, and petty profiles all appear at retail.
VG-10 Damascus
The accessible stainless tier: VG-10 cores under flowing damascus, including black damascus versions. Japanese retail coverage describes the workshop as a damascus (suminagashi) specialist, and this line is where that reputation is easiest to buy into. Easier sharpening than SG2, classic looks, friendlier prices.
Aogami Super Kurouchi / Nashiji (the Kanehiro legacy line)
The carbon-steel line that built the forge's Western reputation, long sold under the old Kanehiro name and still widely labeled that way. An Aogami Super core in stainless cladding with rustic kurouchi or nashiji finish: enormous edge performance, modest maintenance, and a long-standing enthusiast favorite. If a listing says "Kanehiro AS," this is the workshop it comes from.
Ginsan and other runs
Retail maker profiles also list Ginsan (Silver #3) stainless among the workshop's steels, and occasional runs in other combinations appear. Treat these as periodic small batches rather than staples, and verify the steel on the specific listing.
Work for the Masakage brand
Retail documentation from the brand's founding retail partner reports that Yoshimi forges the Masakage Kiri (VG-10), Yuki (White #2, nashiji), and Koishi (Aogami Super) lines, work previously forged by Hiroshi Kato. Note for cross-shoppers: the Masakage Kumo and Shimo lines are Yu Kurosaki's work, not Kato's.
Steel and construction
The Kato workshop's defining material trait is range: it forges modern powder steel, classic stainless, and traditional carbon steel side by side, all sourced from the neighborhood. Takefu Special Steel, the mill behind VG-10 and SG2, is an Echizen neighbor.
SG2: the powder-steel tier
SG2 (also sold as R2) is a powder-metallurgy stainless steel hardened to around 63 HRC, whose fine, uniform carbide structure delivers edge retention far beyond conventional stainless. It asks more patience on the stones and rewards it. Full metallurgy in our SG2 / R2 guide.
VG-10: the proven standard
VG-10, the cobalt-alloyed Takefu stainless that defined the first wave of premium Japanese knives abroad, runs around 60 to 61 HRC in typical hand-forged work: very good edge retention, forgiving maintenance, and the base of the workshop's damascus specialty.
Aogami Super: the carbon flagship
Aogami Super is Hitachi's most heavily alloyed blue paper carbon steel, run here to roughly 63 to 64 HRC per retail documentation, usually behind stainless cladding so only the edge needs carbon-steel care. It takes and holds a ferocious edge; the exposed core will patina with use.
Construction and finishes
Across the range the construction is laminated: a hard core forge-welded inside softer cladding, whether damascus-patterned stainless, plain stainless, or iron. Finishes span polished damascus, black damascus, rustic nashiji ("pear skin"), and dark kurouchi, with traditional wa handles on most lines and Western handles on some. For the vocabulary, see our guide to Japanese knife finishes.
Market presence and availability
Yoshimi Kato's work is documented at retail across the United States, Canada, the United Kingdom and continental Europe, Australia, and Japan, sold primarily through authorized retailers and specialty kitchen shops. In Japan, the workshop sells through Takefu Knife Village's showroom and maintains its own company website; abroad, the knives travel under three labels (Yoshimi Kato, Kanehiro, Echizen Kintaro) plus the Masakage lines the forge produces, which materially widens the brand's effective footprint beyond what the name alone suggests.
Availability follows small-forge physics. The workshop is a handful of craftsmen; popular profiles sell out and return on the forge's schedule, and specialty shops carry rotating selections. The multi-label situation also means the same forge's work can be in stock under a name you were not searching for.
Okami estimate: we place Yoshimi Kato among the most widely distributed single-workshop Echizen makers in Western specialty retail, behind only the celebrity tier (such as Kurosaki) in name recognition, and likely first among Takefu forges in steel-range breadth at retail. Methodology note: this is an approximation built from public information (the company's own site, Takefu Knife Village official materials, and retail assortment observation across specialty knife shops in North America, Europe, and Australia). It is not based on audited sales data; the workshop publishes no sales figures.

Reputation: the honest synthesis
Reading across enthusiast forums, specialty-retailer commentary, and owner feedback, here is the balanced picture. We have no affiliation with the workshop.
What the brand is consistently praised for
- Performance per dollar. The recurring theme: Kato blades deliver grinds and heat treatment comparable to bigger-name forges at meaningfully lower prices. The Aogami Super line in particular has benchmark status among enthusiasts.
- Steel breadth. One forge covering SG2, VG-10, and Aogami Super means buyers can stay with a maker they trust as their tastes evolve.
- Damascus work. Japanese coverage describes the workshop as a suminagashi specialist, and the pattern work is a consistent point of praise.
- Lineage credibility. Training under Hiroshi Kato, in the workshop that also produced Yu Kurosaki, carries real weight in this market.
The recurring criticisms
- Brand-name confusion. Yoshimi Kato, Kanehiro, Echizen Kintaro, and Masakage attributions confuse buyers, and mislabeled retail listings are not rare. It is the price of the forge's history.
- Quiet profile. Compared with the celebrity smiths, Yoshimi has little personal mythology in English media; buyers looking for a story-forward brand sometimes pass him over, which value hunters consider a feature.
- Small-forge finishing. These are hand-forged workshop knives: minor cosmetic variation, rustic choil and spine finishing on the carbon lines, and occasional grind asymmetry come with the territory.
- Availability. A roughly five-person workshop cannot keep every profile in stock everywhere.
Net assessment: among hand-forged Japanese knives in the $200 to $450 band, the Kato workshop is one of the safest recommendations going, especially for buyers who want maker lineage without celebrity pricing.
How to buy authentic Yoshimi Kato
Counterfeiting is not the issue here; label literacy is.
Know the three labels
Blades sold as Yoshimi Kato, Kanehiro, and Echizen Kintaro all come from the same forge. Kanehiro usually indicates the Aogami Super legacy line under the pre-2018 company name; Echizen Kintaro honors the 1948 founder. A reputable specialty retailer will state the workshop plainly.
Where to buy
Buy from authorized retailers and specialty kitchen shops that document their Echizen sourcing, from the Takefu Knife Village store, or via the workshop's own site if you are buying from Japan. As with all small-forge knives, the retailer's direct relationship with the workshop is your authenticity guarantee; we would avoid anonymous marketplace listings where that chain is invisible.
What to verify before purchase
- Core steel. SG2, VG-10, and Aogami Super lines overlap in looks, differ in care and price. Confirm the core on the listing.
- Cladding and reactivity. The damascus lines are stainless; the Aogami Super line is stainless-clad with a reactive edge; occasional iron-clad runs are fully reactive.
- Forger attribution on Masakage. If you specifically want Yoshimi's forging in Masakage form, the documented lines are Kiri, Yuki, and Koishi.
- Era. Pre-2018 Kanehiro-branded blades may be Hiroshi Kato-era forging; current production is Yoshimi's team. Both are legitimate; ask the retailer if the distinction matters to you.
Kato vs the other Takefu names
The natural cross-shop is against the other famous forges of Takefu Knife Village: the Anryu house and Yu Kurosaki's workshop.
| Factor | Yoshimi Kato | Anryu | Yu Kurosaki |
|---|---|---|---|
| Workshop | Kato Uchihamono, ex-Kanehiro (3rd generation) | Anryu Hamono (5th generation) | Kurosaki Uchihamono (founder-led) |
| Forge roots | 1948 (as Kanehiro), renamed 2018 | c. 1873 | Founded by Kurosaki after training under Hiroshi Kato |
| Signature steels | SG2, VG-10 damascus, Aogami Super | Aogami Super, Blue #2 | SG2, Aogami Super |
| Signature look | Damascus and kurouchi, clean and versatile | Kurouchi + tsuchime, rustic | Sculptural hammered finishes (Fujin, Senko) |
| Typical band (gyuto) | ~$250 to $450 | ~$150 to $320 | ~$250 to $500+ |
| Character | Widest steel range, the versatile middle path | Heritage carbon-steel tradition, best value of the three | The celebrity name, boldest aesthetics, highest prices |
The practical read: choose Anryu for traditional carbon-steel character at the lowest entry price, Kurosaki when the signature finish justifies the premium, and Yoshimi Kato when you want the middle path: modern or traditional steel, damascus or kurouchi, from one lineage-verified forge.
