Just bumping to post the M-84 Jet Twister I found a couple days ago. I did a search on Jet Twister, M-84, Robinson Wire Twister, and Safety Wire Pliers and I was a little surprised to see that we didn't have a thread for these on the VB. They mainly show up scattered in threads like this. Although I suppose it is a bit of a one-trick pony. For the longest time Milbar was the only mfgr, and they took over Robinson's operations. These have the 1944 patent on them. Indispensable in aviation and sanctioned motor sports. I can see them being handy for many things. Harnesses. Winches. Any time I have done the hand over hand thing with a vise-grip.
