If you only buy ONE tool then let it be a pair of these Round Nosed Pliers. They are the tool which turns pins into loops and produce the links that join up your designs.
The sister of the round nose is the chain nosed plier, use it for opening and closing jump rings and loops, joining clasps to chains and callottes and for crushing crimps, handy if you don't want to splash out on a crimping tool.
You need a side cutter for shortening headpins and eyepins, cutting tiger tail and other snipping duties.
