I don't want to suggest getting anything NOT from R&T, but as a backup pair of side cutters, I got a pair from my local Sears hardware. If you get the Craftsman brand, you can get them replaced FREE for your lifetime. Comes in handy when you cut heavy metals like memory wire. Sears says they won't chip, but memory wire is harsh on cutters! I'd advise picking up a whole set of pliers from them if you have the cash. They're about บ apiece, and they're a super set to have for cutting and bending metals of all kinds. They have chain nose, round nose, flat nose and bent nose pliers, and quite small side cutters. I haven't had any trouble fitting them into very tight spots. I also have my special German-made tools, but I try not to use them for cutting anything more than beadalon or softflex.
