Steel is an alloy of iron and carbon; the atoms of one element occupy the spaces between the atoms of the other so that the materials are inextricably joined. Most steel also has ingredients to enhance speciﬁc characteristics. For example, stainless steels contain chromium to enhance stain resistance.
Dual Core VG10/VG2
Dual Core steel is used in Shun’s Dual Core series. These two steels are layered, welded, and roll-forged together so that both steels comprise the cutting core of Dual Core. VG2 is a ﬁne grained, high-carbon, high-chromium Japanese stainless steel that takes and holds a very sharp edge. Read about VG10’s excellent properties below.
The newest in the line of VG super steels and is proprietary to Shun. This steel builds on the highly successful VG10 formula by increasing ingredients that take this advanced steel to the “MAX.” VG-MAX™ includes more carbon to improve strength and durability. It has additional chromium for wear and corrosion resistance. Increased tungsten enables the steel to be very ﬁne-grained, so the edge can be extremely sharp. Molybdenum improves corrosion resistance and strength. Vanadium improves impact resistance and enables the steel to form vanadium carbides, which enhance cutting performance.
A complicated blend. In addition to iron and carbon, it contains chromium, manganese, molybdenum, silicon, and vanadium. Most of these elements improve desirable blade characteristics such as wear resistance, corrosion resistance, hardness, and toughness. Vanadium helps make sure the steel’s texture is ﬁne, which is important for Shun’s extremely sharp, long-lasting edge.
A Japanese high-carbon stainless steel with high strength, as well as good corrosion resistance, hardness, and wear resistance. Added vanadium reﬁnes the grain of the steel so that it takes a ﬁne edge.
A Japanese high-carbon, low-chromium (for enhanced sharpenability) stainless steel that has proven to provide an excellent balance between toughness and strength, edge holding and corrosion resistance. Shun uses this steel in applications such as meat cleavers that require a tougher steel and the Classic Fillet for flexibility.
