JST Nippatsu (Japan Solderless Terminal) YC-110R Crimping Tool Manual, One-Handed Tool - Included: Instruction Manual - Model: YC-110R - Type: Wire Stripper Instruction manual included. My husband used this for work. This is a very good tool from JST / Nippatsu. It's about 20 years old, but it was returned to its oiled paper each time it was used and was well cared for, so the condition is good. It's clean ✨ I would like to sell it to someone who needs it (^^) * It opens when you squeeze it tightly until you hear a click.
