FAQs (How To Sharpen Linesman Pliers)

How often should I sharpen my linesman pliers?

Regular inspection is key. Sharpen your pliers when you notice a decrease in cutting efficiency or when the edges appear dull. For heavy use, consider sharpening every few weeks; for lighter use, sharpening every few months may suffice.
