#HDT-50-00 W053752 911049 I believe this is made by TE / AMP, but you should confirm. Professional Ratcheting Crimping / Connection Tool Single Indent Crimp for Solid Pin / Socket. Nose is labelled 20, 16, 12.
Tool is in very good overall used condition. Only some light signs of use in grips and on metal surfaces. Some light dirt in cracks and a few small areas of surface rust on metal finish. Crimp teeth in very good condition. I did not notice any performance issues with them, but they are used so you may find minor imperfections.
