Is there such a thing as a left handed screwdriver, you might be surprised

 

Yes, left-handed screwdrivers are a thing. They are used to tighten and loosen screws that have a left-hand thread. Left-hand threads are used in applications where a screw needs to be tightened against a rotating force, such as in a nut that is being tightened onto a shaft.

Left-handed screwdrivers are not as common as right-handed screwdrivers, but they are available from most hardware stores. They are typically identified by a marking on the shaft or handle that indicates that they are left-handed.

Here are some of the reasons why you might need a left-handed screwdriver:

• To tighten or loosen a screw that has a left-hand thread.
• To repair a bicycle that has a left-hand threaded pedal crank.
• To disassemble a device that has a left-hand threaded screw.

If you are not sure whether you need a left-handed screwdriver, it is always best to err on the side of caution and ask a hardware store employee for help.
