The **Extrema Ratio Dicok** is a diving knife, designed by and for experienced experts.




Extrema Ratio collaborated with divers for the development of the Dicok. This knife can be used in many ways. The blade is made from Böhler N690 steel, which is very corrosion-resistant - an absolute must for divers, This type of steel has an excellent service life. There are two cutting edges: one smooth cutting edge and one side that is partially serrated. The serrated side is ideal for cutting ropes, nets and straps. Indispensable in an emergency. Unlike many other double-edged knives, the Dicok has a blunt tip, so it can be used as a pry tool.



The handle is made from FRN. It has a very rough finish for extra grip, even while wearing diving gloves.



The Kydex sheath is surrounded by a fine nylon fastening system, with leg straps so you can carry it securely. A bright yellow strap keeps the knife in its sheath. It has both a clip that you can easily click loose, and a press stud that you can pull off blindly in an emergency situation.

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

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).
