Materials & coating

Our knives are manufactured in several materials depending on need

Carbon steel

Carbon steel is the cheapest type of knife material, used where sharpness and life span are less important. These blades are used for cutting paper, plastic or rubber and sacrifice durability and wear resistance for feather-like flexibility and a low price.

Chrome steel

Provides greater wear resistance through its higher alloy content, providing improved toughness that’s great for use in demanding manufacturing or packaging environments. Chrome steel usually contains 12 - 13% chrome.

High-speed steel (HSS)

High-speed steel is used in more demanding environments for a slightly better wear resistance than tool steel. High-speed steel contains higher levels of chrome and tungsten.

Tungsten carbide

Used in industry with, for example, continuous operation where a minimised downtime and as long running times as possible for the knives / blades is desirable. Tungsten carbide blades usually last 10 - 20 times longer than knives made of standard steel.

Powder steel (type ASP)

Powder steel is a sintered steel with high firmness and wear resistance. Knives made from powder steel stay sharp significantly longer than other types of steel. Knives made of powder steel can be combined with a counter knife made of tungsten carbide for an unbeatable running time.

Ceramic materials

Ceramic blades are extremely hard and are mainly used as industrial blades (razor blades) in hand tools, but can also be used in other applications. The blades in our safe hand knives from Slice are made of solid ceramics (the entire blade is made of ceramic material). The blades have a finger-friendly grinding angle and are slightly thicker than traditional razor blades. Learn more about safe hand tools from Slice here


TiN = Titanium Nitride Coating
TiCN = Titanium Carbon Nitride Coating
TiN and TiCN are used to protect the knives / blades from wear.
PTFE = (Teflon®) Non-stick coating
PTFE is used to reduce friction between, for example, the knife and the material being cut.
It’s also used to prevent the material being cut from sticking to the blade or knife.
