The **Extrema Ratio N.K.3 K** is a compact neck knife. It is a karambit version of the popular N.K.3. Made for tactical applications. The handle and blade are made from one piece of steel. It doesn't have scales. This makes the neck knife very flat, so you can wear it discreetly under your shirt or jacket.

The knife comes in a sturdy kydex sheath. This sheath has some ring holes and a piece of paracord so you can wear the knife around your neck. Those holes also mean that the holster is easy to attach to a MOLLE system.

## Böhler N690 steel blade

The blade is made from Austrian Böhler N690 steel. This is a stainless steel with long sharpness retention that is also used for surgical tools. N690 is highly durable and can be sharpened until razor sharp.

## Extrema Ratio: Italian knives for professional use

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.

knife_best_use

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).
