Muromoto Ironwork (Made in Japan) Merry Coupling Tool Jr HS120C ($44.28 w/ Free Prime Ship from Amazon Japan)
I know these aren’t cheap, but they’re the updated version of the somewhat popular high end Merry HS175C’s. This new version is more compact than the previous version (that sells around $38 from Amazon) and has coated pincers to be more gentle on brittle electrical connectors. This is by far the lowest price I’ve ever seen on them; they’ve been recently selling in high $60 to low $70 range.
Product Description
Ideal for installing and removing automotive wiring connectors. Tip is flexible material with dip cover. Prevents damage to couplers and scratches while working. Approximately 20% more compact than the previous HS175C. The overall length is short, and it is easier to approach deep areas.
