Quality vs Price

The quality of the steel used in manufacturing your shears is largely responsible for the price you pay. This quality also dictates how long your shears will perform well without the need for servicing. The bottom line is you may pay a higher price up front but you will save time and money in the long run.

The five grades of steel from high to low:

  • ATS-314
  • V10 aka VG10
  • V1 aka Vg1
  • 440C
  • 440A

ATS-314

ATS-314 is the highest grade of steel that is specially made for scissors and shears. The high quality stainless steel produced by Hitachi contains 15% chrome and 4% molybdenum. ATS-314 undergoes the most rigorous processing. This precious metal is rated several times higher than 440C in corrosion resistance, damage resistance and toughness of the blade. It is regarded as one of the best materials used for producing shears.

V10

V10 is Stainless steel originally designed by Takefu Special Steel Company. According to their website (http://www.etokko.com/eng_vg10.htm) : V Gold 10, a high quality cutting stainless steel, is made from highly-selected pure iron material and is worked by best technology, thus VG10 has ductility and shows workability and forgeability. Besides VG10 is free from corrosion caused by impure substances and achieved good abrasion resistance. Our V Steel Series boast these excellent features.

V Gold10 is composed by raw materials and some elements that form alloys.
Addition of 15% of Cr, 1% of Mo and 1,5% of Co makes the matrix (substrate) stronger and prevents carbides from dropping out. By adding V, the structure becomes finer. Added Cr, Mo, and V form a lot of hard carbides, so abrasion resistance improves which gives knives long-term clean cutting, VG10 is rather machinable and easy to grind. VG10 also has quadratic effect in high-temperature tempering that it is ideal use in cutting tools which are given surface-coating at up to about 450℃.

440C

From Penn Stainless: “Grade 440C stainless steel is a high carbon martensitic stainless steel. It has high strength, moderate corrosion resistance, and good hardness and wear resistance. Grade 440C is capable of attaining, after heat treatment, the highest strength, hardness and wear resistance of all the stainless alloys. Its very high carbon content is responsible for these characteristics, which make 440C particularly suited to such applications as ball bearings and valve parts.”

440A

In the same familly as 440C steel, but of lower quality, and not as strong. 440A is rust resistant but not as highly recommended as it’s 440C cousin.
