Bernstein 4-380 Watchmaker's screwdriver

Precision screwdrivers, also known as micro screwdrivers, are used in precision mechanics for small screw sizes or miniature screws. The hard precision blade made of quality tool steel allows for direct engagement with the mini screw and provides optimal torque transfer. The sturdy plastic handle with a rotating cap fits comfortably in the hand, and the colored ring facilitates work by enabling quick identification of the required size.

The blade (HRC 58-61) is made of molybdenum-vanadium steel and is blackened. The handle is made of plastic. Care instructions: High humidity or touching blackened blades with fingers (sweat) can lead to surface rust. Therefore, the blades should always be kept dry or, if stored for a long time, coated with oil. If surface rust does form on the blade, it can be easily removed with a light sanding.
