Yes, I meant use the jigsaw to cut the lid, 1/4 inch in from the lid
first. Then cut petals from the saw cut to the rim, then bash the

having a go.

Er... your jigsaw will put the same half-dozen to dozen teeth of the blade
against the metal, depending on the stroke of the saw. These will dull
eventually.

You could then fit a new blade (assuming a surfeit of metal blades).

However: attaching a scrap of wood or Something(tm) against the sole plate of
the jigsaw (using screws, bolts, duct tape, cable ties, ... don't freehand it,
that doesn't work!) will bring a fresh batch of teeth into play, as it lifts the
sole plate away from the metal. You are then using a fresh section of the worn
blade, a bit further out.

The blade is a bit more likely to break used like this -- but the alternative is
to throw it out... nothing to lose!
