PB Swiss Tools screwdrivers have a longer working life thanks to a stronger tip! The combination of raw material, heat treatment, and the highest standards mean that your tool will out perform in every situation. All PB Swiss Tools are manufactured using a special spring steel alloy and heat treating process that has been developed over the past 130 years. In spite of the high hardness of 58 - 60° HRC, their tools have an excellent toughness and elasticity. One of the most critical components of a screwdriver is the tip. PB Swiss Tools manufactures each screwdriver above all international quality standards to ensure that each critical contact point matches the corresponding fastener to produce the most durable screwdriver. PB Swiss Tools also give and bend when put under pressure, they don’t just snap off! Other screwdrivers claim that they can withstand the pressure, but only PB is able to bend their screwdrivers over 90 degrees without any sign of fracturing. Other manufactures may use standard tool steel or even high torque steel, but PB Swiss Tools screwdrivers are guaranteed to be the hardest, strongest, and longest wearing tools on the market!
