Install one of the cutoff cutters.

Align the snips with the line you want to cut with the upper blade of the tin snips touching the sheet metal. Hold the tool tight. Partings involve cutting the sheet metal along two paths simultaneously. Each cut punches out a tiny piece of the sheet metal and the process is repeated.
