You can't beat a 3M crimper
This purchase was to replace my previous 3M crimper that was over 20 years old. Replaced a few parts over the 20 years but basically flawless over that time. They are not cheap but we crimper around 60 crimps per day on average. Built to last and work well.

They are the industry standard in the NC sport fishing custom boat building industry. There is no substitute. I averaged 200+ crimps daily for 10 years.
