Power Shears operate in much the same way as '''[[scissors]]''' or '''[[Tinsnips|snips]]''' with two small blades powered to slide against each other. Nibblers work more like a '''[[Bench Shears and Guillotines|notcher]]''' and are based around a small punch and die which is powered repeatedly up and down to remove small bits of metal and leave a '''[[kerf]]''' approximately 6 mm wide.
