For the production of PB Swiss Tools tools, we use a special spring steel produced especially for us. A very high hardness value and a unique durability and springiness characterize our special steel which we have developed through the decades with our steel suppliers.

A possibly high degree of hardness is the prerequisite for a first-class hand tool so that the wear and tear remains low. With over-stressing, the tools may not suddenly and without advanced warning break or even splinter. The durability of the material thus determines and limits the admissible hardness.

Thanks to the special PB Swiss Tools spring steel, in spite of the high hardness of 58 - 60 HRC, our tools have an excellent toughness and elasticity.



High hardness (HRC 58-60)
