The Niolox steel low profile version of the DPx HEST Original survival tool. The spare-no-expense knife for those who keep a low profile. The DPx HEST Original changed the way adventurers think of a brutal-use survival blade. Some customers wanted more: more cutting, more hardness, more options. We responded. With two versions. DPx Gear is proud to add a harder, sharper, longer-lasting DPx HEST fixed blade tool complete with hollow, black, American-made G10 handle; revised pry bar angle; a 0.19-inch thick, 61 Rockwell hardness survival tool made of Niolox tool steel. All with a black satin TiCN PVD coating.
