Karbonstahl
Die „Hagane“-Messer aus Karbonstahl sind die Wahl für fortgeschrittene Benutzer und Profis, die eine hervorragende Schneidleistung suchen. Sie erfordern zusätzliche Pflege, aber es gibt viele Liebhaber von Karbonmessern wegen seines besonderen Vorteils in der Schneidleistung. Wir bieten hochwertige handgeschmiedete Karbonklingenmesser von Japans besten Handwerkern und Schmieden.
Karbonstahl wird typischerweise als eine Legierung aus Eisen und Kohlenstoff definiert, in der der Hauptbestandteil der interstitiellen Legierung Kohlenstoff ist (zwischen 0,12 und 2,0 %). Einige Definitionen besagen auch, dass ihre Gesamtmasse nicht mehr als 1,65 % Mangan und nicht mehr als 0,60 % Kupfer enthalten sollte. Im Gegensatz zu Edelstahl enthält Kohlenstoffstahl nur wenige oder keine Elemente, die die Korrosion reduzieren, was bedeutet, dass er sich relativ leicht verfärben und rosten kann. Folglich erfordert es mehr Pflege und Wartung als rostfreier Stahl.
We recommend that you do not leave Carbon Steel knives in wet conditions or in contact with water for any significant length of time because it can cause discoloration and eventually lead to rusting. If you often work with wet foodstuff, please keep a soft absorbent cloth or towel nearby so that you can frequently dry the knife whilst working. We similarly recommend that Carbon Steel knives that come in to contact with salty foods or liquids should be cleaned as soon as possible in order to prevent corrosion. It is normal for an oxidized ‘patina’ to develop on knives which are used with acidic foods or foods which contain a lot of protein. Some people like this discoloration and it does not affect cutting performance, but it can easily be removed using cloth and some mildly abrasive cleaning powder, such as Bar Keepers Friend. This cleaning method will minimize the chance of damaging the appearance of the knife. To remove more serious corrosion and rust we suggest using the ‘rust eraser’ type of abrasive rubber blocks, starting with the finest abrasive version first, to minimize damaging the appearance of the knife.
It is also especially important to dry the blade and handle of Carbon Steel knives after hand washing because any remaining water might lead to discoloration and eventual rusting. Before storing the knife, we advise that the blade is given a very light coat of a non-perishable oil that is relatively P.H. neutral, such as camellia oil (Tsubaki Oil), jojoba oil, Ballistol All-purpose Oil, or mineral oil. Place a small drop of the oil on a soft clean cloth, kitchen paper, or a disposable tissue. After oiling, please put the blade back inside the folded piece of corrosion-inhibiting paper that it was originally shipped with, as it will help to prevent corrosion.
Having read about the special care and maintenance that Carbon Steel kitchen knives require, you might wonder why some people prefer them to Stainless Steel knives. Some people continue to use Carbon Steel knives due to their respect for cultural traditions, whilst others believe that they offer a better balance of edge sharpness, edge retention and ease of sharpening than Stainless Steel knives. Indeed, because many culinary professionals need a knife that retains maximum sharpness throughout their long working day that is also easy to sharpen, they prefer to use High Carbon Steel knives. This is why they are very popular with professionals who make dishes that use raw ingredients, such as Sashimi (Raw fish) and salads, since the ingredients have to be cleanly cut in order to retain the best possible texture and flavor (Roughly cut surfaces frequently suffer from excessive oxidation, which can spoil the flavor of the food). Many knife enthusiasts also prefer Carbon Steel knives because, unlike Stainless Steel knives, they can build up a patina which they believe adds personality, history and beauty to a knife.
Just as the legendary cutting performance of Japanese swords made of Tamahagane (“Jewel Steel”) is known worldwide, Japanese Carbon Steel kitchen knives also offer excellent cutting performance. In fact, the high purity Shirogami ("White Steel”) group of steels, which are made at the Yasugi steel works of Hitachi Metals Ltd., were originally developed to emulate many of the desirable qualities of Tamahagane (“Jewel Steel”). Hitachi use White Steel No.2 as the starting point for creating many of the other steels which they produce, including White No.1 steel, the Aogami ("Blue Steel”) range of steels and also Aogami Super steel.
Stainless steel
The Stainless steel knives are most popular for rust resistance and ease of maintenance. Our stainless steel knives are made of Japan’s advanced technology high quality stainless steel that combines high carbon and other high performance alloys, so you can enjoy both of the rust resistance and longer edge retention.
Stainless steel has typically been defined as any steel alloy which has a minimum of 10.5% Chromium content by mass. However, due to the development of Powdered Metallurgy Steels that contain a lot of Carbon (Which can form Chromium Carbides and thus reduce the corrosion resistance of the steel), one steel manufacturer has suggested a new definition in which a steel is only considered to be ‘stainless' if the Chromium content is twelve times higher than the Carbon content. One key benefit of Stainless Steels is their high corrosion resistance, which makes them easy to maintain when compared to Carbon Steel knives, which rust fairly easily if not properly cared for. Stainless Steel knives are particularly useful for our customers who often work with moist or wet foods, salty foods, or acidic foods such as fruit. A further benefit of Stainless Steel knives, as long as they do not contain a significant volume of other alloying elements, is that the Chromium forms bonds with some of the Carbon and produces Chromium Carbide, a very hard ceramic compound that increases the edge retention of knives.
Cutting tools made from early Stainless Steels had a reputation for being relatively difficult to sharpen and also poor edge sharpness, but since the latter part of the 20th Century this has no longer been the case. Due to years of research and development the Stainless Steels that are available today offer excellent performance in terms of corrosion resistance, edge sharpness, edge retention and ease of sharpening. Sometimes you may hear or see some modern Stainless Steels being referred to as “High Carbon Stainless Steels”, this is because they have a relatively high carbon content and also compare favorably with ‘ regular' High Carbon Steels in terms of edge sharpness, edge retention, and ease of sharpening. All of the Stainless Steel knives that we carry are made from “High Carbon Stainless Steel” and they proved to be very popular with many of our customers who desire knives that are not only easy to care for, but and also have very good cutting performance
