How to choose the right carpet knife blade

When choosing the right utility knife blade, it is important to understand how the different SK-grade steels differ from each other. SK-grade steels such as SK2, SK4, SK5 and SK7 differ significantly in their carbon content and its effects:

• SK2: This steel contains the most carbon (0.90–1.04%), which makes it very hard and sharp. It is best suited to cutting tools that need a hard, wear-resistant blade. Because of its hardness, however, it is more brittle and more prone to breaking, which limits its use in heavy work​
• SK4: The carbon content of SK4 steel is slightly lower (0.95–1.04%), and it offers a good balance between hardness and flexibility. An SK4 blade is very durable but slightly more flexible than SK2, which makes it more versatile in the manufacture of cutting tools, although it is still more prone to breaking than SK5​
• SK5: SK5 contains 0.80–0.90% carbon and offers a good combination of hardness and durability. It is slightly softer than SK2 and SK4, but more flexible and less prone to breaking. This makes it an excellent choice for general use, such as utility knives and other tools that need both hardness and some flexibility​
• SK7: SK7 contains the least carbon (0.60–0.70%), which makes it the least hard of these steel grades. An SK7 blade is the most flexible, but it is not as hard as SK2
  or SK4. It suits lighter cutting work where flexibility is more important than maximum hardness​

Choose the right steel according to the materials and the requirements of the work: SK2 and SK4 are best suited to precision work and hard materials, while SK5 gives better durability in heavy use.

Warnings

Handle the blades with care, as they are very sharp. Always wear protective gloves when changing blades and keep spare blades out of the reach of children.

Product comparison

Yato SK5 spare blades stand out from their competitors thanks to their excellent material. Compared with many cheaper alternatives, the SK5 blade is more durable and stays sharp longer. For example, many traditional utility knife blades, such as Stanley and Olfa blades, use softer steel, which makes them less durable for heavy use than Yato’s SK5 spare blades.
