Indeed. Perhaps make the cut 1/4 inch or so in from the rim, then go
around the edge with tinsnips, cutting from the edge to the rim, then
bashing the 'petals' downwards with a heavy hammer. All a bit long and
drawn out, but better than lacerated fingers.

I'd stick with the jigsaw.

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
petals downwards. Very wet here today, otherwise I'd be out there
having a go.


Yes I meant I'd stick with jigsaw rather than tinsnips to cut your
petals...

Petals are OK, you may have catchy bits around the joins. If hammering,
hold a big lump of wood (e.g. a woodburner log) on the outside like a
panel beaters' dolly. Or rest the edge on a wood chopping block if you
have one, and rotate so that you are always using the block as an anvil.

Or, bend them over with a mole wrench and finally "pinch" the top edge.
