How to choose the right carpet knife blade



When choosing the right carpet knife blade, it is important to understand how different SK blades differ. SK-grade steels, such as SK2, SK4, SK5 and SK7, have significant differences in their carbon content and its effects:



    SK2: This steel contains the most carbon (0.90-1.04%), making it very hard and sharp. It is best suited for cutting tools that require a hard and wear-resistant blade. However, its hardness makes it more brittle and prone to fracture, which limits its use in heavy-duty applications

    SK4: SK4 steel has a slightly lower carbon content (0.95-1.04%) and offers a good balance between hardness and flexibility. SK4 steel is very tough, but slightly more flexible than SK2, making it more versatile in the manufacture of cutting tools, although it is still more prone to fracture than SK5

    SK5: SK5 contains 0.80-0.90% carbon and offers a good combination of hardness and toughness. It is slightly softer than SK2 and SK4, but more flexible and less prone to cracking. This makes it an excellent choice for general purpose applications such as carpet knives and other tools that require both hardness and a degree of flexibility

    SK7: SK7 contains the least amount of carbon (0.60-0.70%), making it the least hard of these grades of steel. SK7 is the most flexible steel, but it is not as hard as SK2

or SK4. It is suitable for lighter cutting jobs where flexibility is more important than maximum hardness



Choose the right steel according to the materials and job requirements: SK2 and SK4 are best suited for precision work and hard materials, while SK5 offers better durability for heavy duty use.



Warnings



Handle 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 steel blades stand out from their competitors due to their excellent material. Compared to many cheaper alternatives, SK5 steel is more durable and retains its sharpness for longer. For example, many traditional carpet cutters, such as those from Stanley and Olfa, use a softer steel, making them less resistant to heavy use compared to Yato's SK5 Varadors.
