Found in a box belonging to my grandfather, a cutlery shop owner who passed away in 1969. These are three insulated, penetrating circuit testers from over 50 years ago. They have handles for applying force. I think the penetrating design is interesting and unusual. They are unused, but are vintage items that have been stored for a long time. There are scratches, scuffs, dirt, and rust. Please understand and accept these vintage items. Thank you for looking.
