Extrema Ratio - Sethlands D2 - Black

“Extrema Ratio Sethlans” is a fixed blade work knife created to deal with a wide range of situations, suitable for survival, bushcraft, prepping, but also as a backup blade.

The Sethlans was designed in collaboration with Daniele Dal Canto, Master Master Advanced instructor.

The Sethlans is available in two versions with two different types of steel.

Black version that uses D2 steel, heat and cryogenically treated at 60 HRC, which has a high resharpening capacity even with makeshift tools.

To give greater 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 freeing the skeletonized structure of the knife, allowing 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 made up of a very light and minimalist Kydex part.

It can be disassembled and can be adapted to both left- and right-handed users.

The addition of an optional belt clip allows both vertical and horizontal positioning of the knife and makes the sheath much more versatile than the textile version.

It is equipped with a mini pouch with MOLLE system containing a double-sided sharpening stone and a Firesteel for lighting fires.
