Why? In taking apart electronics i find uses for most of the parts. Things which can not be reused go into scrap piles for recycling. But these sheets couldn't be easily reused and probably can not be recycled. I tried using overhead transparency sheets that had been printed on for a customized clear wallet pattern but the sheets mark when folded or creased. These circuit sheets are extremely durable.
A desktop computer keyboard (for the circuit sheet and a metal piece as a straight edge)
A screwdriver to open the keyboard
A ruler or tape measure
A cutting board or cutting mat
A razor knife
A roll of clear packing tape
The fine folks at HowCast have made a video from my Instructable...
