The Best Keiun Scissors for Hairdressers
Keiun is made by Yamamura Manufacturing Co., Ltd., a Sanjo City blacksmith founded in 1948 in Niigata Prefecture. The company developed the ATS-314 specification and builds the Keiun line on Damascus steel — stainless steel and cobalt alloy layers forged under sword-smith Shigeyoshi Iwasaki's supervision. Five picks here run from $280 to $950, all made in Japan.
What are the best Keiun scissors?
The Alto YTK, around $280, is Keiun's entry Damascus cutting shear — Stainless Damascus over a cobalt alloy core in 5.0 to 6.0 inch, suited to blunt and chop cutting. The Alto NY, around $400, uses the stainless steel and cobalt alloy construction with a mirror finish across 5.0 to 6.0 inch. The Kokaji, around $440, is a Damascus cutting shear in two blade models — YL and CR — across 5.5 to 6.25 inch, suited to both slide cutting and everyday work. The Half Damascus Narrow Blade, around $595, uses a partial Damascus pattern with a narrow blade profile designed for detail work and slide cutting in 5.5 and 6.0 inch. The Damascus, around $950, is the Keiun flagship — full Damascus stainless steel and cobalt alloy layers with a unique moire forging pattern, hand-finished in Sanjo in 5.5 and 6.0 inch.
All five picks use Damascus steel — a construction in which stainless steel and cobalt alloy are forged in layers to produce a patterned blade. The practical distinction across the range is the number and arrangement of layers and the blade profile. The Alto YTK and Alto NY are the entry and mid points: both use Stainless Damascus over a cobalt alloy core, with the Alto NY offering a mirror finish. The Kokaji adds blade model variety — YL and CR cuts — for stylists whose cutting style calls for a specific blade configuration. The Half Damascus Narrow and Wide models use a partial Damascus pattern: Yamamura applies the Damascus to half the blade and treats the remainder with guard-tempering, giving a blade-specific cutting feel. The Damascus flagship takes the full Damascus layer count to its highest point, with each pair unique due to the moire pattern produced during forging.

The Keiun Damascus range
Keiun is made by Yamamura Manufacturing Co., Ltd., a Sanjo City blacksmith in Niigata Prefecture founded in 1948. Yamamura developed the ATS-314 steel specification and builds the Keiun line on Damascus steel in house under sword-smith Shigeyoshi Iwasaki.
Damascus in Keiun’s context means stainless steel and cobalt alloy forged in alternating layers. The pattern formed in the surface during forging is a moire or wave motif produced by the differing alloys. The practical properties of each model depend on which alloy pairing Yamamura uses, how many layers the blade carries, whether the Damascus is full-blade or partial, and whether the profile is narrow or wide. The Alto family covers entry and mid cutting; the Kokaji and Half Damascus models sit at the mid-to-upper tier; the Damascus flagship is the top of the range.
All Keiun scissors are made in Japan.
