WHAT IS HANDTOOLS?

A hand tool is a device for performingwork on a material or a physical systemusing only hands.

EXAMPLE OF HANDTOOLS

Long nose pliers Side cutter Tweezers Wire stripper Screw driver

PLIERS

Function :

• One of commonly used tools in electronics shops• cutting and gripping•To bend, re-position and cut wire • Given their long shape, they are useful for reaching into cavities where cables (or other materials) have become stuck or unreachable to fingers or other means

SIDE CUTTER

•Tweezers are tools used for picking up and manipulating objects too small to be easily handled with the human hands.

•They are probably derived from tongs, pincers, or scissors-like pliers used to grab or hold hot objects since the dawn of recorded history.
