Reviews and articles >> Kasumi knives

We are very proud to inform, that MyGoodKnife became an official dealer of Kasumi knives (SUMIKAMA Cutlery) in Finland and Estonia.
Since 1916, SUMIKAMA has been devoted to manufacturing high-quality and value-added cutlery using the over 780-year traditions of Seki swordsmiths and its outstanding skill to harmonize new technologies with new materials.
Entering to the world market only in 1990-ies, company have managed to stand on a par and even became more successful than many of the famous manufacturers of knives from the Japanese city of Seki.
The Gifu Seki Cutlery Industry Association comprises of 53 companies in and around Seki. The cutlery industry in Seki is characterized as its multi-product and small-lot production, by which various new products based on the combination of traditional craftsmanship and modern taste are produced.
The origin of the Seki cutlery industry dates back to the 13th century, when Motoshige, a master swordsmith from the Kyushu region moved to live in the area. A lot of master swordsmiths appeared after Motoshige. However, when peace time came in the late 17th century, sword demand fell and some swordsmiths turned to blacksmiths making agricultural tools, such as knives and sickles.
Now kitchen knives (50% of domestic share), pocket knives are produced in this area and exported to Europe and the US. Seki is now recognized as a cutlery town comparable to Solingen in Germany. The recent trend of Japanese food outside Japan, especially in Western countries, is on the side of the popularity of Seki cutlery.
For sure, it is very difficult to survive and even stand out in such competition in Seki. But Sumikama company have done it. Their way can’t be called easy, however, as the way of any real Japanese warrior. Company Sumikama was founded in 1916, but knives Kasumi became famous only in the late 1990s. Today Kasumi knives is the symbol of best Japanese quality. When we talk about high-end professional chef’s knives from Japan, the first name that comes to mind – is Kasumi. Perhaps the secret of company, that Kasumi offers to western customers not only a long tradition of production of Japanese knives, but absolutely modern technology and materials. Almost all of the series Kasumi are made from VG10 steel.
MyGoodKnife store would like to represent you beautiful Kasumi HM series.
The super hard alloy VG-10 is used as a core material of the blade. This knife has a three-layered structure that holds the core material with corrosion-resistant stainless steel from both sides.
The middle layer that forms the cutting edge, called Hagane. Two layers those cover and protect hard cutting edge are called Jigane. Exсept protect role, they are also make whole blade more flexible. In general, whole this “sandwich” of three layers called Warikomi. Traditional Japanese kitchen knives are forged from two layers and have only one sharp side (like for example sushi-knives). So only one side should be protected by more flexible layer. Interesting, that this “sandwich” of two layers get name Kasumi. In English “Kasumi” means “mist”. And when you look to part of blade where Hagone and Jigane are join to each other – it is really looks like beautiful swirls of mist.

Hammered Series knives pattern are hammered with many tiny indentation creates air pockets when cutting to prevent food from sticking. Hammer pattern on both sides of the blade is a result of hot forging by 300 tons of a flection machine which makes the steel stronger hammer design clear. Special tempering of the VG10 blade core create an edge retention that far surpasses other brands of similar kitchen knife. The handle is made in POM, material that makes it comfortable, resistant, hygienic and long lasting.

Kasumi manufacture recommends using whetstones to keep the edges razor sharp. If your knife edge is in bad condition, start sharpening with the #240-300 rough grit of the whetstones. If your knife is in average condition, start with the #1000 medium grit of the whetstones. These two grits will keep your Kasumi knives sharp enough for normal home use.
To give your knives a professional razor sharp finish, you will also need to use fine whetstone. After sharpening your knives with the #240 and/or #1000 grit, proceed with the #3000 fine grit. After that you could proceed with #8000 grit. The #8000 grit has been specially developed for super finishing knives. The #8000 grit is almost the same grit and quality like natural whetstones used to sharpen Japanese Samurai swords. You can find required whetstones in range of Mygoodknife.
All Kasumi knives have a nice individual package.

Please remember, that Kasumi knives should not be washed in dishwasher, and wash with ordinary neutral detergent or just water by hand. Then wipe with soft towel to maintain the best condition and for longer use.
The blades have a hardness Rockwell HRC 59-60 representing the ideal hardness for kitchen professional knives of high quality and guaranteeing the best cutting and tight performances of the cutting-edge and having a longer duration with respect to the major part of other knives.
Kasumi knives are produced by small-scale. Each knife goes through several stages of sharpening and finishing by blacksmith’s hands. Such a tradition of manufacturing swords and knives in Japan, during the long processes, the master, of course, gives the knife a part of himself. People in Japan believe, that through such way of production, knife gets a soul and becomes an extension of the hand of a warrior… or a Chef.
