The J1931BST is a compact 5-inch folding knife built around AR-RPM9 stainless steel, a material chosen for edge retention and corrosion resistance in demanding conditions. The 4-inch black PVD-coated drop point blade pairs with a smooth stainless handle and thumb pull opener for reliable one-handed deployment, while the pocket clip makes it practical daily carry across Europe. Button lock engagement keeps the blade secure without sacrificing speed, and the included nylon case plus boxed presentation suit both active use and collection.
