Mini bolt cutters, was it? Or was that someone else? Good method I've found for cutting, is to place the wire into the cutter, and then turn it until the edge "falls" off the cutter's blade. You should hear/feel a tiny "click" as it falls that minuscule amount and becomes flush with the cut edge. Snip then, and it's about as good as bolt cutters can get. Also, with my 1/2" galvy I cut them three at a time, but with 1/4" I have to do them one at a time. Doing sets of 3 is a lot easier, but in general yes, cutting is the worst part of the whole thing.
When joining rings, it helps if you bend and unbend them towards their center. That is, don't simply pull one end up and the other down to open it. Push one end up and left, and the other down and right, to align them closer together, and then when closing the ring, do the same thing. I often have to push the ring past the closed position and get a good grip on the pliers to push the ring together strong-arm style. If the rings are small enough, you can fit the entire the into the pliers and give it a very detailed squeeze to hem it up a little. Just be careful, if you over-squeeze and the ring slips and pops closed, then you've ruined the ring. Never fear though, a ring ruined like this can become a clasp! To do this, take a ring. Place the pliers on either side of the split, and pull it open. Then take one end, and put the pliers over the entire ring, and pinch it down until the tip of the edge hits the wire itself, making a tiny loop. And thus, you have a hook, which you can attach to the end of a bracelet or necklace and hook into itself. Bonus points: it's made of the same material and size as the piece itself, so it blends beautifully, and is extremely cheap and easy. Most cut rings aren't sharp enough to snag clothing, or can be sanded a bit as needed (or just rubbed against a rock, any friction really works).
Also, for fun, try looking up a byzantine chain style, it's relatively easy once you figure out how it's done, and looks gorgeous if done right. Don't worry so much about how people show to do things, I've starting making all weaves 1 ring at a time, or 3 at a time for euro. People say to make little "modules" or "units" of weave and then connect them, but I just can't get into that. Do what works for you, you're the one putting out the effort.
Now, with my bronze and aluminum here, I'm going to work on a special little project. It's a surprise though, hopefully it'll be done tomorrow :3
Fun fact: bronze is extremely tough to work with. The idea of working with stainless steel or titanium terrifies me.
