Step 4: A handy tool worth having

Picture of A handy tool worth having
The photo shows a wire stripper tool for household electrical work. These are available in many tool departments, particularly in the electrical tools at a big box store. They are not expensive to buy. 

Although useful for stripping wire sizes commonly used in homes and for pinching crimp connectors, this one also has five holes on each side of the tool for cutting screws of different common sizes without damaging their threads. The screws for cabinet hardware are 8-32 in thread size (#8 diameter screw, 32 threads per inch).
