I have a Knife and I did my pull-pull like Paul's diagram shows. I had to debur the inside of the aluminum pieces. Mine had a slight bur, so make sure you check this to avoid cutting into the wire when crimping. I have a tiny round file that has a tapered point that I used for this, worked like a charm. I crimped the assembly snugly, then put CA on it. It has been bulletproof so far and I have no fear of it ever failing.
