The Sethlans D2 Black is a fixed-blade tool designed for demanding field use—bushcraft, survival and general outdoor work. The Black variant uses D2 tool steel (thermally and cryogenically treated to 60 HRC) with an EXP DARK protective coating to enhance hardness and wear resistance. Blade geometry and a flat grind, combined with a tapered thickness from 6.3 mm down to 4 mm, deliver a reliable balance of strength and cutting performance. G10 handle scales offer ergonomic grip and are removable to reveal the skeletonized full-tang for weight saving or paracord wrapping. The package includes a lightweight, removable Kydex sheath configurable for left/right carry and a M.O.L.L.E mini-pouch with a dual-grit sharpening stone and a firesteel.

Concluding sentence: a robust, low-maintenance field blade built for real outdoor tasks, offering modular carry options and useful survival accessories.
