Shinko Kurokumo R2 Black Damascus Gyuto 210/ 240mm by Shiro KamoI am super glad to offer you the Shinko Kurokumo by Master Shiro Kamo. The concept of the Kurokumo is very similar to my Syousin Chiku Migaki line: people really like a standard line, so I make up a even better custom line based on it. In this case of Shinko Kurokumo, Shinko () is the K&S in house brand and the Kurokumo (, black cloud) represents the acid etched damascus pattern.

I am super glad to offer you the Shinko Kurokumo by Master Shiro Kamo. The concept of the Kurokumo is very similar to my Syousin Chiku Migaki line: people really like a standard line, so I make up a even better custom line based on it.

In this case of Shinko Kurokumo, Shinko (辰光) is the K&S in house brand and the Kurokumo (黑雲, black cloud) represents the acid etched damascus pattern. The knife itself is idential to the Syousin Suminagashi namely same profile, same grind and the same core-steel (R2). 

Extra compared to the standard Syousin Suminagashi

  • Acid etch the blade to give it a more pronounced damacus pattern,
  • Rounded choil and spine

The Steel

R2 is a type of PM steel (Powder Metallurgy) that is long regarded as the best all-rounder steel for kitchen knives. The PM process produce a very fine grain for the steel, so it gets sharper than the traditional non-PM steel; the added Vanadium and Molybdenum give the steel excellent wear-resistance and toughness, means it is less likely to chip and keeps the edge much longer.

The wear-resistance property of PM steel can sometimes be a double-sword for kitchen knives. That is, if the blade is made of mono-steel construction (non-cladded, usually done by stock removal), the excellent wear-resistance property means the bevel is notoriously hard to thin and refinish (generally speaking all the monosteel knives are more or less like so, but PM steel is that much harder).

Now the beauty of sanmai construction kicks in. Sanmai literally means “three pieces”: a thin layer of core steel is sandwiched between two layers of soft iron or stainless steel. Doing so not only allows the knife to cut as good as a monosteel knife (core steel doing the work), but more importantly, enables the knife to be thinned with ease (removing the soft cladding rather than a hard steel with hardness over HRC 60). In the case of Syousin Suminagashi line, the soft cladding is even hand forged by Kamo-san with an eye catching Damascus pattern.

About Shiro Kamo

Shiro Kamo, while little known overseas, is a well regarded knife smith in Japan. He was awarded the prestigious “Dento-kogeshi” (Master of Traditional Crafts) at a very young age (total of about 10 persons are awarded in Echizen area, likes of Takeshi Saji and Katsushige Anryu). He is also the president of the Takefu Knife Village Cooperative (http://www.takefu-knifevillage.com/company/) that is the reason I say while not known by many of us outside, Kamo-san is certainly a highly regarded figure in the kitchen knife industry. His knives have exceptional profile and grind, and the heat treatment of R2 steel is so impressive that you are assured to be getting a damn good knife. I just can’t afford to not offer his work to you :D

Good purchase ! I recommend this one
Color: Purple
⭐️⭐️⭐️⭐️⭐️ Stylish, Functional, and Surprisingly Durable — A Great iPad Companion I’ve been using this purple case with a built-in keyboard for my 9th generation iPad, and I’m genuinely impressed with its overall quality. It hits the mark in several key areas: 🔹 Design & Aesthetics: The color is I purchased was a light purple—elegant without being overly flashy. It adds a pop of personality to my setup, which I appreciate. The stitching and build look well-finished, giving it a premium feel. 🔹 Keyboard Functionality: The attached keyboard connects easy and holds a strong charge. The keys are surprisingly responsive for a compact layout, and the typing experience is smooth and tactile—not mushy like some others I’ve tried. Great for emails, journaling, or casual work on the go. 🔹 Protection & Durability: The case feels sturdy without being bulky. It offers solid protection, especially around the corners, and the iPad feels secure when clipped in. After tossing it into bags and using it daily, it still looks and feels great—no odd flex or signs of wearing down fast 🔹 Touch & Comfort: The material has a soft-touch finish that feels great in the hand. It’s not slippery, and it doesn’t attract fingerprints easily. It also makes it comfortable to use the iPad in different positions—typing, drawing, or watching shows. 🔹 Extras & Usability: I like that the case doubles as a stand and supports multiple angles. The magnetic closure is a nice touch, keeping everything secure when closed. Overall, this case+keyboard combo offers a lot of value. It’s functional, stylish, and reliable—exactly what I was hoping for. If you’re looking for a practical upgrade that doesn’t sacrifice style or quality, I’d say this one’s worth a look.

Pretty Color & Lighting
Color: Pink
I found myself needing a keyboard case for my iPad pro (10.5 inch). I stumbled across this one with great reviews. Once I opened the box it arrived in, it lived up to its reviews. The case feels smooth and appears to have great quality. The keys on the keyboard sound like a typewriter which I love. I was unaware that the keyboard lit up but to my surprise the lighting was extremely bright even in the daylight. The weight of the both the keyboard, iPad, and case all together feels as heavy as a FiveStar notebook. Connecting the keyboard to the iPad was the easiest part because once you pop your iPad in the case and turn on the keyboard and press the connect button you head to the bluetooth settings of your iPad to pair them. Performance wise sometimes the keyboard snoozes after a few minutes of not being used and takes a second to start typing again. Besides that it works great when you’re constantly typing. Overall I love the color of the case and it’s definitely a money spent well.

Good value for the money
Color: Purple
This is a great little case. This is used for my elderly aunt and uncle’s ipad which doesn’t get a lot of use. The case is protective and opens up to hold the ipad at a couple of different levels. The keyboard is not as smooth as the apple keyboard I have for my own ipad but it really works well, holds a charge for a long time and was a great price.

The keyboard fits nicely inside for easy travel. It charges easy and comes with a charger for usb. It connects when on and turns off if not in use to conserve the battery.
