EXTREMA RATIO: SETHLANS

Image

EXTREMA RATIO SETHLANS” is a fixed blade work knife born to face a wide range of situations, suitable for survival, bushcraft, prepping, but also as a backup blade.

SETHLANS was designed in collaboration with Daniele Dal Canto, Master Advanced F.I.S.S.S. instructor (Italian Federation of Sports and Experimental Survival).

SETHLANS is available in two different versions with two different kinds of steel.

The stone washed version is produced with Böhler N690 heat treated at 58 HRC, chosen for the reliability it has demonstrated over the last 20 years due to its resistance to oxidation and durability of the edge.

The black version is produced in D2 steel, heat and cryogenically treated at 60 HRC, which presents an high resharpening capacity even with makeshift tools. In order to give greater qualities of hardness and resistance, the blade is coated with the new Teflon-based product “EXP DARK”, proposed by Extrema Ratio.

The knife comes with G10 grips that feature the ergonomic design characteristic of Extrema Ratio handles. They can be removed by releasing the skeletonized structure of the knife, that allows maximum lightness with minimum thickness. For lovers of extreme customization, the full-tang structure allows the handle to be covered with a paracord cord.

The sheath is composed of a part in very light and minimalist Kydex. It can be disassembled and can be adapted for both left and right handed users. The addition of an optional belt clip allows the knife to be positioned both vertically and horizontally and makes the sheath much more versatile than the textile version. It is also equipped with a mini pouch with M.O.L.L.E. system. containing a two-sided stone for sharpening and a firesteel for lighting fires.

The retail price of both Sethlans versions is € 395,00.
