Using these electrician's scissors is easy. For cutting cables up to 14 AWG, place the wire in the cable - cutting notch and apply pressure. To strip 19 or 23 AWG wire, use the appropriate stripping notches. When deburring electrical boxes, insert the tip notch and run it along the edges. The serrated teeth ensure a good grip while cutting. When cleaning wire, use the scrapers on the blades. As for maintenance, keep the blades clean and dry after each use. You can use a soft cloth to wipe off any debris. Avoid exposing the scissors to excessive moisture or harsh chemicals. If the blades seem dull over time, you may need to have them sharpened by a professional. And always store the scissors in a safe place to prevent damage.
