Best tool for cutting sheet metal in longer lengths.

[JF.]

I need to adjust 4 sheets for my Lindab Båstad click-roof. Each sheet is 180cm so I'm wondering which tool is best for cutting longer distances. Nibbler?

Pelican scissors work well for long straight stretches.

A regular right- or left-handed scissors works excellently. It is admittedly more efficient to cut with a pelican, but an ordinary pattern scissor suffices since there are no longer lengths to be cut.
