Gents: there are a number of swaging pliers available but the T-185, from <SAVACABLE.com> are, in my opinion, the best.
I have done hundreds of cables with them (including some special optics drive cable) and have NEVER has a failure.
The key to a god swage, besides havint the right tool, is using a proper swaging tube. I use only annealed copper tubing in a size that will allow three passes of the cable.
They also sell the finest cable cutter I have ever used. Not cheap but the best usually isn't.
