Pliers
Ther are more types and qualities of pliers out there than I would ever even want to discuss here. There are a few though that I find to be essential. Each pic below is linked to JewelrySupply.com site for each type of pliers. Generally, tools are like most things, in that you get what you pay for. So buy the best you can afford. Don't go cheap on tools, especially the tools that you use a lot. You'll save dough initially, but replace them more often.
