5160, a spring steel. Popular steel for forging swords and large knives, with high toughness and good wear resistance. [citation needed] Popular sword manufacturers that use 5160 spring steel include Hanwei and Generation 2. [citation needed] 5160 spring steel is mainly used on Medieval type swords. [citation needed] 4140 [definition needed]
Spring steel is a name given to a wide range of steels [1] used in the manufacture of different products, including swords, saw blades, springs and many more. These steels are generally low-alloy manganese , medium-carbon steel or high-carbon steel with a very high yield strength .
Schrade Cutlery [47] and Spyderco use 154CM, 440C, D2, S30V, S60V and S90V steel, [48] [49] [50] and Ernest Emerson's knives are hard-ground from differentially heat-treated A2 tool steel. [51] Emerson Knives machines blades from 154CM steel, [ citation needed ] and Mike Snody uses A2, S35V , 154CM and 440C steels.

Compared to conventional European knives such as J. A. Henckels or Wüsthof, GLOBAL knives are made from a significantly harder alloy of steel and use a thinner blade. In addition, the cutting edge of the blades are ground at a more shallow 15° angle, which produces a sharper knife that also hold its edge for longer and allows for more accurate work.
In 2009, Crucible Steel introduced an update to CPM-S30V to meet the needs of renowned knife maker Chris Reeve that they called CPM-S35VN. The addition of 0.5% Niobium, and reductions in both Carbon (from 1.45% to 1.40%) and Vanadium (from 4% to 3%) produced an alloy with 25% increase in measured Charpy V-notch toughness over S30V (Crucible claims 15-20% improvement).
The quenched-steel is first sanded or polished, to remove any residual oxidation, revealing the bare metal underneath. The steel is then heated in a localized area, such as the hammering-end of a chisel or the handle-end of an axe. The smith then carefully gauges the temperature by watching the tempering colors of the steel. As the steel is ...
Abrasion resistant steel is a high-carbon alloy steel that is produced to resist wear and stress. There are several grades of abrasion resistant steel, including AR200, AR235, AR400, AR450, AR500 and AR600.
