This is a small but useful tip we got from talking to David at uCHobby about lead trimming. When leads are clipped they usually go flying off and are a pain to clean up as well as an eye hazard. By resting a finger on the tip of the lead while clipping, the lead just falls to the table. It’s faster than grabbing the sides of the lead, although with thicker leads (voltage regulators, some diodes, etc.), grabbing the sides is more prudent unless you don’t mind a lead hanging out of your finger.
