KUROMAKU is the world's first set of colour-coded sharpening stones, each colour representing a different grade of coarseness in the range. The storage case makes it easy to carry the stones, and can also be used as a sharpening base. These stones are Waterstones but can also be used as oilstones.

Every stones case can be stacked for easy storage and helps identify the grit quickly by the colours.

Rubber feet on the base of the case provide a stable working surface for mobile sharpening, the base of the case is ventilated so the stones can dry properly and prevent cracking.

#320 Grit Kuromaku Whetstone 

  • Splash & Go - The Kuromaku stones do not absorb water like some other whetstones do. This means that there is no soaking required prior to using them. Get them wet, and begin sharpening. No time spent waiting for them to absorb water..
  • Fast Cutting - Kuromaku stones sharpen very fast. They are among the fastest cutting of whetstones. Whether you are sharpening for yourself or for a client, they are perfect for getting an edge very sharp.
  • Hard Wearing - No one likes the time spent flattening water stones, and while the M15 do need to be flattened, they require less flattening less often than inferior quality stones, saving valuable time for the professional or serious home sharpener.

Shapton's Kuromaku range is available in the following grits:

#120 (White) Extremely Coarse Grit. 

The White #120 is formulated for quick steel removal in stainless and powder metals and can easily set the working edge quickly.

#220 (Moss) Very Coarse Grit.

The Moss #220 is formulated for quick steel removal in stainless and powder metals.

#320 (Blue-Black) Coarse Grit. 

The Blue-Black #320 is formulated for quick steel removal in stainless and powder metals, it is less aggressive than the 120 and 220 stones.

#1000 (Orange) Medium to Coarse Grit.

The Orange #1000 is a very popular intermediate stone and is great for moderate stock removal. This stone is good to use prior to polishing.

#1500 (Blue) Medium Grit.

The Blue #1500 is a slightly finer intermediate stone but It still has a reasonably fast stock removal rate yet still starts to polish the bevel.

#2000 (Green) Medium Grit.

The Green #2000 stone is a very popular finer intermediate stone and it still has a reasonably fast stock removal rate yet starts to polish the bevel.

#5000 (Wine) Fine Grit

The Wine #5000 stone is the first polishing stone. It can still remove some metal but is primarily a polishing stone. It is more dense than most other whetstones.

#8000 (Melon) Very Fine Grit

The Melon #8000 was originally designed for fine woodworking tools requiring an extremely fine edge. It will leave a light mirror finish. It is a fantastic polishing whetstone.

#12,000 (Yellow) Extra Fine Grit

The Yellow #12000 was originally designed for fine woodworking tools requiring an extremely fine edge. It will leave a bright mirror finish. It is a serious polishing whetstone.

Maintenance

The Shapton Kuromaku series of stones will begin to develop a dish after frequent usage, to maintain the stones a lapping plate is recommended to keep the surface flat for long life.

We suggest either the Jende Industries Glass Lapping Plate, Shapton Diamond Glass Lapping Plate or the Shapton NAORU cast iron lapping system for this process.

How To Use

Soaking the Kuromaku stone is not necessary as it is a Splash & Go stone.

Once finished sharpening, clean the stone and allow it to air dry naturally in a shaded position, rapid drying can cause cracking, and leaving the stone in water can cause the stone to degrade.

FAQ

Q: Which face of the KUROMAKU series sharpening stones should I use?

A: You can use either face, but we recommend that you start on the side where no letters have been printed.

 

Q: Recent KUROMAKU stones look different from the designs bought in the past. Is there any difference in spec?

A: No. The only change was in the printing design, not in the quality or specs of the stones.

 

Q: Are any of the KUROMAKU sharpening stones recommended for normal household knives?

A: We recommend the Orange Medium (1000) sharpening stone and Wine Fine (5000) finishing stone. If you intend to use only one stone, we recommend the Blue Medium (1500) sharpening stone.

 

Q: I want to try using "KUROMAKU Purple", but the 'Precautions' state it should be used after "KUROMAKU Melon" － would it be OK to use it for sharpening after "KUROMAKU Yellow" instead, as this is finer?

A: That would be fine with high hardness steel, but for blades made from softer materials, please do use "KUROMAKU Melon". This is due to the stones' physical characteristics.

The Island Of Death
Format: Hardcover
On August 7th, 1942, American Marines stormed ashore on Guadalcanal. What lay before them was a six-month odyssey of fighting against the best of what the Japanese had to offer. In this fine book, author Joseph Wheelan describes the battle that turned the tide in the Pacific War. The Japanese had started construction of an airfield on Guadalcanal. If completed, Japanese aircraft would be able to harass American convoys and threaten Australia. The Americans seized the airfield and eventually, planes from the Cactus Air Force began attacking the Japanese. Throughout the book, the reader learns about all phases of the Guadalcanal campaign, including the battles of Alligator Creek and Bloody Ridge. On the sea, the Americans and Japanese slugged it out at Savo Island, as well as the great naval battles of November, 1942. Names such as Chesty Puller, John Baslone, "Archie" Vandegrift, Joe Foss, and "Bull" Halsey became household names in the United States. Each side lost many men, ships, and planes, but the tenacity and, finally, the industrial might and the ability to rapidly replace losses, led the Americans to victory. Never again would the Japanese regain the offensive in the Pacific War. "Midnight in the Pacific" is a very good book, and the author has done a good job of describing all of the main points of the battle. Each chapter is broken down into a single month's worth of action, and the narrative is well-written. Highly recommended.

Good Narrative History
Format: Hardcover
The account of the Guadalcanal campaign was well-written. It has several good maps but it falls short with the two carrier battles associated with the action. There should have detailed maps for the Battle of the Eastern Solomons and the Battle of the Santa Cruz Islands. Aside from this shortcoming, the book provides an excellent, readable history of a crucial confrontation between the US and Japan.

A Very Thorough Accounting of One of the Most Savage Battles of World War 2
Format: Kindle
My father served in the United States Marine Corps during World War 2 and fought in the first offensive battle by the US during the war, the battle for the island of Guadalcanal. He was seriously wounded there and evacuated back to the states where he spent a year in a naval hospital. As a result, I have read many of the books about this battle. This book was particularly interesting because the author described the battle from the perspective of both the allied forces and the Japanese, drawing from historical records and other books. It was a very thorough accounting and demonstrated what a monstrous battle this was. I only wish my father were still alive so that I could have discussed it with him. His experience at Guadalcanal was not something he would often talk about, but considering savagery of what he saw and endured, I understand. If you are interested in Guadalcanal, I recommend this book.

Excellent book on the Campaign!
Format: Hardcover
I highly recommend this book! I have read many books on the Guadalcanal Campaign and I rate this one at the top. It has just the right blend of stragity and personal accounts to keep the story interesting. It is actually a real page-turner, which is rare for a non-fiction work. Wheelan writes in a style that reminds me of the books I read in my teens by Cornelius Ryan and John Toland, which captured my interest in WWII and history. The book jumps right into the invasion, no multiple chapters concerning the planning and build up, but this info is covered later. All phases of this campaign are covered; ground, air and sea. The maps are okay. There are never enough. The author skims over much of the U. S. Army battles after the Marines are relieved, but that seems to be a trend in all of the books on Guadalcanal that I have read. Overall, this is an excellent book for those who want to learn about the campaign and those who need a re-fresher after reading Starvation Island and Guadalcanal by Frank in years past.

Most complete coverage of Guadalcanal I have read.
Format: Kindle
I have read dozens of WWII books and many touched on the Guadalcanal Battle. I thoroughly enjoyed The Big E and its involvement in the battle. Thas book covered the entire conflict from start to finish. Frankly, I hated to see the book end. The courage and tenacity of all those involved was amazing. To understand the miserable conditions in the area where these men fought was inspiring. To see this battle through the eyes of the American forces and Japanese forces was an added bonus. Thank you for a great read!!!
