Avionic snips (aka compound-action snips) come in three cutting styles - straight cutting, left cutting and right cutting. I plan to work with roofing corrugated steel and have no idea in advance what cuts exactly I'll have to do. Buying all three styles seems an overkill.
I guess straight cutting won't very versatile if I have to make some tight curve cut, so I have to choose between left cutting and right cutting.
Which style do I choose if I have to choose exactly one style without knowing the exact cutting patterns in advance?
