Atlantis's Damascus Steel
Damascus or pattern welded steel is the process of combining at least two different types of steel to achieve mechanical properties or to achieve a desired aesthetic. In our Damascus we use three different types of steel all of which harden and temper in the same temperature range. These steels are forge-welded together. This means that a sandwich of these different types of steel are assembled at room temperature and tack welded together then they are put into a forge running @ 2350 F, at this temperature the steel becomes "plastic" and "sticky" then the steel is placed into a press where, under high pressure these different steels are fused together. This process is also called defusing bonding. Molecules actually move back and forth across this interface between the different steels thereby bonding the materials together. The billet, as it's called is then stretched folded and manipulated to create desired patterns or just folded a number of time to achieve a desired layer count. Production knives on the market today claim 7-16 layers per side. Our knives are made from at least 400-600 layers of steel. Some blades have over 1,000 layers. This process is very labor and material intensive. In some cases up to 70% of the material is lost or sacrificed along the way to achieve a desired pattern. This is why Damascus knives are in general much more expensive that the regular steel knives. In our regular steel “Hamon line” chef knives employ the same clay tempering as was used in sword-making.
We see our Damascus knives as a piece of the master knife master’s soul. This process requires more of the knife master’s time and a higher level of concentration than the regular steel knives. When we designed the regular high carbon steel knives our goal was to design the highest performance blade, which experience and skill could bring to bear. The regular high carbon steel (Hamon) is tempered to 2,700 F plus degrees to render it almost indestructible.
Damascus blades are made of different types of steel whose many layers extend right through the cutting edge. These layers wear at a slightly different rate causing a very fine micro serration which can be very helpful in staying sharp longer. Both sharpen exactly the same way and both get equally sharp, so it's in the way that they wear which is different. So in deciding which type of steel you prefer, think of the Damascus as an art piece, as well as, a functional tool.
