About Keiun
Keiun is a Japanese professional scissor brand manufactured by Yamamura Manufacturing Co., Ltd. (Yamamura Seisakusho), a blacksmithing company founded in 1948 in Sanjo City, Niigata Prefecture. Sanjo has a long history as one of Japan’s premier metalworking towns, and Keiun draws on that heritage.
The brand is known for its Damascus steel patterned scissors. Damascus steel involves layering multiple types of steel together, which creates the distinctive wavy surface pattern and can improve blade performance. Keiun states that these scissors are built by artisans in house at their Niigata facility.
Product Range
Keiun produces cutting scissors, thinning scissors, and left-handed scissors. Their thinning shears cover several removal rates: 15 to 20%, 25 to 30%, and 50 to 60%. They also offer models designed for slide cutting.
The brand is carried by a few U.S. and international retailers, including Shear Integrity and Scissor Dude, which makes them accessible to American stylists looking for authentic Japanese Damascus shears.
Heritage
With roots going back to 1948, Yamamura Manufacturing has over seven decades of metalworking experience behind the Keiun line. Sanjo City’s blacksmithing tradition stretches back roughly 300 years, and several other scissor and knife makers operate in the same region. This concentration of skilled metalworkers is a defining feature of the area.
Market Positioning
Keiun sits in the mid range price tier. The Damascus finish sets them apart visually from most competitors at a similar price point. For stylists who want Japanese craftsmanship with the look and potential performance benefits of Damascus layered steel, Keiun is worth researching.
Yamamura Manufacturing: The Steel Behind ATS-314
Keiun scissors are produced by Yamamura Manufacturing (山村刃物製作所), located in Niigata’s Tsubame-Sanjo region. Yamamura’s significance to the Japanese scissors industry extends far beyond their own brand:
- Introduced 440C stainless steel to hair scissors in Japan
- Developed the ATS-314 specification — manufactured to Yamamura’s formula by Proterial (formerly Hitachi Metals). Yamamoto Scissors documents ATS-314 as “VG-10W + (SECRET)”
- Supplies forged blanks with ura-suki (裏スキ) already processed to other scissor manufacturers
- Produces Damascus/laminated steel for the scissor industry
Buying Keiun scissors means buying from the company that develops the steel other brands use. Source: Yamamura Manufacturing (Japanese).

Considerations & Trade-offs
Steel & Edge Performance
Keiun (慶雲) is the finished scissors brand of Yamamura Manufacturing — one of the most important companies in the Japanese scissors industry. Yamamura introduced 440C stainless to hair scissors, developed the ATS-314 specification (manufactured by Proterial/Hitachi Metals to Yamamura's formula), and supplies forged blanks with ura-suki processing to other manufacturers. Keiun scissors use ATS-314 and Damascus steel directly from this source — there is no intermediary in the steel supply chain.
Value Assessment
Keiun's unique value is steel provenance: scissors made by the company that developed ATS-314 and supplies steel blanks to much of the Japanese scissors industry. This is the equivalent of buying wine directly from the vineyard owner. Premium pricing reflects both the ATS-314 material (VG-10W + proprietary additions) and the Damascus options. Brand recognition outside Japan is limited — Keiun is a craftsman's brand, not a marketing-driven one.
Service & Support
ATS-314 is harder than standard VG-10 (comparable HRC 59-60 but with enhanced properties from proprietary additions). Qualified sharpeners experienced with premium Japanese steels can service these scissors.
Best For
- Stylists who care about steel provenance and want scissors from the company that develops the steel itself
- Those seeking ATS-314 or Damascus without the markup of larger retail brands
- Professionals who value authenticity over brand recognition
Consider Alternatives If
- Buyers who need extensive English-language support and wide retail availability
- Those unfamiliar with Japanese scissor brands — Keiun requires knowing what you want
- Budget-conscious buyers — premium materials at premium pricing
