Ceramic Blade Materials Differ

Many industrial companies are considering switching from metal-blade cutting tools to ceramic-blade cutting tools as the latter become 

more available and more popular.

Unfortunately, hasty web research is likely to turn up information that lumps all ceramic blades together, when in truth they are not 

all created equal. Misinformation and false claims abound.

The truth is, Slice® is the only manufacturer that makes a truly safer blade. Our grind is safe to the touch, and it’s proprietary. 

But there’s more to know.

Ceramic Blade Materials Differ

Slice ceramic blades, whether it be our utility knife blades or box cutter blades, are made of 100 percent zirconium oxide, also known 

as advanced ceramics or engineered ceramics.

In fact, what is the difference between a ceramic blade and a metal blade? How is the material used for ceramic blades different from 

what we are in daily contact with? Let’s start with the history of ceramics.

Advanced ceramics are used to manufacture high-performance and reliable components, such as advanced semiconductor packaging and 

automotive engine parts. In fact, advanced ceramics support various latest technologies in modern society.

Through more than ten thousand years of making ceramics, humans have learned modeling techniques. Produce ceramic products of various 

shapes.

However, mastering the technology of manufacturing precision ceramics and applying them to cutting tools originated in Japan in 1985. 

Due to the uniqueness of its materials, ceramic knives are quickly and widely used in factories, offices and homes, and become 

indispensable in daily life around the world.

Different from general ceramics, the advanced precision ceramics used to make HEWER MultiCERA ceramic blades contain 100% zirconia; a 

white crystal with a melting point of about 2700°C and a boiling point of about 4300°C, with extremely high stability, which make 

the trimming operation easier.

HEWER MultiCERA ceramic blades contain a variety of unique features, including wear resistance, never rust, non-conductive, high 

density, high hardness, no pores, no dirt, thin and sharp, easy to clean and high safety.

HEWER MultiCERA ceramic blades are suitable for many industries, including aviation industry, automobile manufacturing, packaging 

manufacturing, etc.
