The **Extrema Ratio Sethlans** is an outdoor knife made for survival and bushcraft. It's also great as a backup knife alongside a larger knife. The Sethlans was designed in cooperation with Master Advanced F.I.S.S. instructor Daniele Dal Canto (Italian Federation of Sports and Experimental Survival). The blade is 4 mm thick, high and has a full flat grind. This makes the knife better suited than most Extrema Ratio knives to food prep and other everyday cutting tasks. 

This version of the Sethlans has a D2 steel blade. A version with Böhler N690 steel is also available. What's special about the Sethlans is that you can remove the scales to make the knife slimmer or to add a paracord wrap.

You can carry this knife in a kydex sheath that attaches to a nylon MOLLE-compatible system. The sheath also comes with a mini MOLLE-compatible pouch with a double-sided sharpening stone and a firesteel. 

## D2 steel blade

The blade is made from D2 steel. This is a tough tool steel that retains its sharpness well. It's also easy to sharpen, which is handy if you use the knife often. Do, however, be careful with rust: D2 is not completely stainless. Extrema Ratio has addressed this by adding a coating to the blade.

## G10 handle

The handle is made from G10: fibreglass with an epoxy base. This is a high-quality, robust plastic.

## Extrema Ratio: Italian knives for professional use

The Italian brand Extrema Ratio has been producing sleek tactical knives for professional use ever since 1997. This includes first responders such as soldiers, police officers and firefighters. Extrema Ratio knives are made to adhere to the highest military standards. These knives are produced in cooperation with the Italian army which carefully tests and carries them. The result: proven, top-quality products. Unparalleled in the world of tactical knives.

General information

We always measure the blade height at the highest part of the blade.

Blade height

We always measure the blade length ourselves. This is the length of the blade from the tip to the front of the handle. This may deviate from the manufacturer's specification.

Blade length

value_blade_length_edge

The length of the cutting edge is measured from the tip to the start of the edge. This may deviate from the manufacturer's specification.

Cutting edge length

We always measure the blade thickness at the thickest part of the blade. Often just before the handle. This may deviate from the manufacturer's specification.

Blade thickness

value_handle_length

We always weigh a product as bare as possible. Knives and axes always without their sheath, lights (if possible) without their battery. For knife sets we measure the entire weight. This may deviate from the manufacturer's specifications.

Weight

Dimensions & weight

value_steel_hardness

The hardness in Rockwell C for a knife is always according to the manufacturer's specifications. When a manufacturer specifies a value of 56-58HRC, for instance, we always note the highest value, i.e. 58HRC.

We like to highlight what use the manufacturer had in mind, or what we believe the knife is suited for

Best use

This concerns the type of edge [Want to learn more about a serrated versus a plain edge](/en/ct/pocket-knives-difference-plain-edge-serrated.htm)?

Type of edge

molle_compatible

MOLLE is a mounting system that allows you to attach sheaths and other accessories to backpacks. With this specification we indicate whether a product is already MOLLE-compatible by default. [Want to learn more MOLLE](/en/ct/what-is-molle.htm)?

MOLLE-compatible

We measure the sharpening angle ourselves. This value is the angle per side.  So 20º means that the total angle of the edge is 40º. Please note that knives are almost always sharpened by hand, even in factories. This value is therefore only an indication of a single tool measured by us. You are always free to choose your own sharpening angle. [Learn more about sharpening angles](/en/ct/sharpening-angles-explained.htm).

Sharpening angle

In terms of grind we are talking about how the complete blade thickness extends into the edge. Want to learn more about grinds? [Read all about grinds on knives](/en/ct/knife-grinds.htm).
