## Blade made of CPM Magnacut steel
The blade of this Benchmade Water Class is made of CPM Magnacut steel, possibly the most revolutionary steel of the 21st century. MagnaCut offers an unrivalled balance between sharpness retention, toughness, corrosion resistance and ease of sharpening. Since the release of CPM MagnaCut in 2021, it has become one of the most popular steels in the world of knives. The MagnaCut blade of this pocket knife measures 11 cm in length.

## History of CPM Magnacut 
This type of steel was developed by Dr Larrin Thomas, a metallurgist who has dedicated his career to improving knife steel. He is the son of Devin Thomas, a famous damascus smith who supplied Chris Reeve Knives with steel for many years. Dr Larrin Thomas works in the automotive industry but is passionate about knife steels. He thought it should be possible to do better, and together with Crucible Industries came up with CPM MagnaCut.

The ‘stonewash’ process was chosen for the finish of this blade. The stonewash process involves the blade being placed inside a drum with ceramic stones, or media, and then vibrated or tumbled for several hours. The result is a finish that looks precisely polished or roughened depending on the version. The advantage of stonewashing, however, is that signs of use are much less noticeable. That makes it a popular choice for knives that see a lot of use.



## Benchmade Water Class: knives for fishermen and maritime use
Benchmade's Water Class knives are made for maritime purposes; from recreational fishing and kayaking, to use at sea while sailing and deep-sea fishing. The blades within this series are made of corrosion-resistant materials such as CPM MagnaCut steel. The sheaths and handles are also designed to withstand wet conditions. Ideal for all your active activities on rough waters.



## About Benchmade
Benchmade was founded in 1987 by Les de Asis in California. It began as a small company producing butterfly knives. With a strong commitment to innovation and quality, Benchmade quickly grew and moved to Oregon, where it expanded its production capacity. A signature feature of Benchmade is the Axis lock, which is also used by other brands today.

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

value_max_belt_width

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

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).
