What many love about this steel is how although it is a stainless steel, and has the better qualities of stainless steel, it also has qualities of a carbon steel alloy. Carbon steel, unlike stainless steel, is easier to sharpen and achieve a good edge. ELMAX is a generally new steel, and was not stocked in the United States until late in 2009. Since then, it has become very popular, and is now available in single sheets as well as cut bars from distributors. Now it can be found in myriads of knives that are produced by various companies. ELMAX steel is a "high chromium-vanadium-molybdenum-alloyed steel," made of 1.7 percent carbon, 18 percent chromium, .3 percent manganese, 1 percent molybdenum, .8 percent silicon, and 3 percent vanadium. This composition allows for the metal to have a high wear resistance, high compressive strength, superior corrosion resistance, and a very good dimensional stability, or the ability to retain its size and form even after taking abuse. When hardened to 57-59 HRC, though the steel can actually be ground up to 62 HRC, the knife has a good edge holding ability as well as a less-commonly found impact resistance- which is much higher than other stainless steels- and grinds as easily as the 154 CM steel, which is renowned for its easy grinding ability. Therefore, ELMAX steel can take more abuse than other metals, and come out unscathed. ELMAX knives can be used for multitudes of purposes, and can be found in knives in a wide range of categories. This steel is ideal for survival/Bushcraft knives, with qualities that are crucial for outdoor and survival activities. When you are outdoors, camping or hiking, you need a knife that can last and perform to the highest standards of durability, toughness, high wear, and corrosion resistance. Knives used for such outdoor purposes can often be found in less-than-ideal situations such as heavy rain, situations in which it would be risky to use most knives for fear of wear or corrosion. With ELMAX, however, avid outdoorsmen can enjoy the stress-free convenience of a high-abuse taking, quality blade. In addition to survival, these metals are ideal for use in blades meant for hunting, fishing, and even kitchen work, where sharpness and robustness are critical features. The United Sttes Navy SEALS are utilizing the "First Edge 5150" ELMAX Full Tang Survival Knife. Having been a supply man for SEAL Team unit, anything The USN SEALS us is worth having.
