Damascus - "Forge Welded" or "Pattern Welded" multi layered steel knife blades.

Damascus Steel - Wikipedia Definition:
Damascus steel is a type of steel that was used in Middle Eastern swordmaking, starting in the 3rd century.      These Damascus Steel swords are characterized by distinctive patterns of banding and mottling reminiscent of flowing water. Such blades were reputed to be tough, resistant to shattering and capable of being honed to a sharp, resilient edge. Damascus steel is superplastic and very hard at the same time.

The Blades are made by hammering and folding several layers of hot molten steel, usually from 256-512 layers, into a single ingot.  This gives the blade a destintive "designers" look.


My blades are typically: 512 LAYERS:  ( 8 FOLDS)
HARDNESS: 59 ON ROCKWELL SCALE C 

Blade Material: 15N20 & 1095 Hand Forged 

Damascus steel was originally made from wootz steel, a steel developed in India before the Common Era. The original method of producing  Damascus steel is not known. Because of differences in raw materials and manufacturing techniques, modern attempts to duplicate the metal exactly have not been entirely successful. Despite this, several individuals in modern times have claimed that they have rediscovered the methods in which the original Damascus steel was produced.​

During the smelting process to obtain Wootz steel ingots, woody biomass and leaves are known to have been used as carburizing additives along with certain specific types of iron rich in microalloying elements. These ingots would then be further forged and worked into Damascus steel blades, and research now shows that carbon nanotubes can be derived from plant fibers, suggesting how the nanotubes were formed in the steel.

​History - 
The original damascus was likely produced from ingots of wootz steel, imported from India and Sri Lanka and later Persia.   Archaeological evidence suggests that the crucible steel process started in the present-day Tamil Nadu before the start of Common Era. The Arabs introduced the Indian wootz steel to Damascus, where a weapons industry thrived.   From the 3rd century to the 17th century, India was shipping Damascus steel ingots to the Middle East.

San Mai Damascus:
San Mai “Damascus” is a variation of forge welding that refers to knives with the hard steel hagane forming the blade's edge and the iron/stainless forming a jacket on both sides. In stainless versions, this offers a practical and visible advantage of a superb cutting edge of with a corrosion resistant exterior. San Mai steel is three layers forge welded together. The two outer layers are multi layered ingots of the same type and often referred to as the jacket (bread) and the middle layer is referred to as the core (meat).  Overall, most high quality San Mai blades consist of 133-265 layers.

San Mai is a Japanese technique now in
widespread use in Japanese style and non-Japanese style knives. It translates to “three layers.”


My San Mai Damascus blades are typically stainless steel:    440C core - 440 and 420 damascus outer layers,

hardened to RC 58-60. Outside billits reange 64-132 layers, totaling, complete blade 133 to 265 layers.

 

Stainless Steel - 420
Type 420 is a martensitic stainless steel that provides corrosion resistance similar to Type 410 plus increased strength and hardness. It is magnetic in both the annealed and hardened conditions. Maximum corrosion resistance is attained in the fully hardened condition. 420 is a little softer than 440 however it is "tougher".

Stainless  Steel – 440 c
Type 440C is considered a high-end stainless steel. It is very resistant to corrosion and is one of the most common stainless alloys used for knife making.   The once ubiquitous American Buck Model 110 Folding Hunter was made of 440C before 1981. 440C has highest carbon content in 440 group.
