ApexUltra is a steel truly worthy of handcrafted knives. It is a low alloy design that is forgeable, forge-weldable, and its fine carbides make the steel relatively easy to finish and sharpen. With its high purity and well-balanced alloy composition it has very high toughness in the 66+ HRC range along with excellent edge retention. \u003cspan data-mce-fragment=\"1\" class=\"s2\"\u003eThis product offers an excellent combination of properties for knives.
