Introduction

PB Swiss Tools has always been considered as the absolute best quality among hand tool manufacturers. A tool with an age of more than 137 years, which is considered to be the most luxurious type of hand tool and is used in sensitive industries such as helicopter and airplane maintenance. The quality and service life of this company’s tools are famous all over the world. The metal part of this company’s screwdrivers is made of steel. PB Swiss Tools uses spring steel for the production of tools, which is produced exclusively for this company. The hardness of this steel is very high (58 to 60 HRC). The high hardness of the produced steel and its unique durability and spring ability are the result of decades of effort by steel suppliers for Swiss Tools products. The handle part of the classic and multipurpose PB Swiss Tools tool is produced from cellulose butyrate acetate (CAB). Cellulose butyrate acetate is a modified natural material produced from wood. Since this natural substance may have an unpleasant smell inside the drawer and closed spaces such as tool boxes, vanilla essential oil is used to make this smell pleasant.
The PB 515 screwdriver set consists of a handle with the ability to rotate at the end along with eight replaceable blades, each of which has two series. The series and the handle are placed inside a bag that is rolled and becomes a small cylinder.
