Different methods work, I have used successfully: a heavy duty paper
guillotine and a sheet metal shear.

There are small relatively inexpensive shears available.

The other recommended method is to use a water-cooled tile saw --- again
relatively inexpensive, the water captures most of the dust.

I have also used a abrasive cutting disk on a dremel -- poor cut and
very messy. Table saw -- messy. The dust is relatively toxic, so this
is a poor method.
