In addition to the red, green, and yellow snips, often referred to as "aviation" snips, are these "offset" snips. These are from Snap-On (left) and Wurth (right) and are a little more expensive than the aviation snips. Note how the jaws are offset to one side. These snips are available in straight, left, or right cut, just as the aviation snips are. The Wurth snips shown can handle steel up to 1.8mm thick. These are twentysomething years old and still going strong, though the blades have seen some abuse over the years!
