Shinko Kurokumo R2 Black Damascus K-Tip Gyuto 210mm 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. The knife itself is idential to the Syousin Suminagashi namely same

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

Excellent chair/great support.
Color: Black Full Mesh, Style: Executive
Excellent, comfortable chair! I was surprised at how easy it was to assemble---but the directions were super clear and all the pieces and parts were labeled. Once I received the chair, I was also surprised with the email follow up from Alice at Molents. All this for a reasonably priced chair.

Great Ergonomic Support and Fit, with Minor Adjustment Caveats
Color: Black Full Mesh, Style: Executive, Color: Black Full Mesh, Style: Executive
As someone who is 5'4" and 140 lbs, the size of the chair feels ideal, and the seat cushion is spacious without feeling overwhelmingly large. The breathable mesh material is high quality, keeping me cool during long working sessions while still feeling sturdy. The back support and adjustable lumbar feature aligns perfectly with my spine and has noticeably reduced my posture fatigue. The height adjustment mechanism operates smoothly to align perfectly with my desk, and the assembly process was surprisingly straightforward, taking less than 20 minutes with clear instructions and tools included. My only slight hesitations are regarding armrests not being long enough. The wheels are not easy to roll on carpet and require a bit of extra effort to move. Maybe a chair mat might be helpful on carpeted floors. However, for the price, the comfort and build are impressive.

High quality and incredible customer service
Color: Black Full Mesh, Style: Executive
This is an extremely well made chair at a very competitive price. The packaging, assembly instructions, as well as the way the hardware was packaged and labeled is probably the best I've seen. I'm particular about tools, and the included allen wrench was better than the normal "included tools" so much so that i actually used it rather than one of my own. The assembly was easy, and the chair itself looks and feels very high quality, and is very comfortable. Perhaps best of all was the level of customer service. I emailed on a weekend to activate the warranty and request the free cushion they offer. I got a personal response in less than a day and they offered upgraded wheels for free as well. This is a company worth doing business with.

Great product AND customer service!
Color: Black Full Mesh, Style: Executive
I'm having a hard time writing this review because I can't tell which one I like better: the product or the customer service! I work on a computer all day, so a comfortable office chair is critical for me. This chair is great - it's adjustable in every way I need it to be, especially the armrests. The breathable mesh is both durable and supportive, and is more comfortable to sit in than the "overstuffed" chair it replaced. Let me just say: no company provides better customer service than MOLENTS. Right after assembling my chair (which was very easy, btw), I registered for the 2 year warranty they offer. The NEXT DAY I received an email from Alice in their customer service department 1) to confirm my warranty, 2) to tell me about the free foam seat cover they were sending me, and 3) to make sure the chair was comfortable and easy to assemble. Very few companies take the effort to follow up with customers right after making a purchase like that. I'm extremely happy with this purchase. This chair is worth MORE than it's weight in gold, and I strongly recommend to anyone thinking about buying an office chair to buy it from MOLENTS - you won't regret it. Oh, and if Alice's supervisors are reading this: she absolutely deserves a promotion!

Great value and a good chair
Color: Black Full Mesh, Style: Executive
Great chair for the price. Not as solid as an Ergo but it's not thousands of dollars either. It's pretty easy to assemble and the directions are good. It rolls well on LVP flooring and they offer 'upgraded' wheels at no cost from what I can tell. I didn't order them since the included ones work perfectly. I'm 6'4" and both the seat and arm heights can be adjusted to fit me well. The mesh seat is comfortable and the back works fine. The only downside for me is that the lumbar support doesn't adjust quite high enough to actually reach my lumbar area, but I think it would work for most folks. Overall it's hard to argue with the cost and even if it only lasts a few years it's worth the money.
