Of course the ring-pull closures are incompatible with butterfly

If they are tough, I sometimes use a wooden spoon handle through the
ring, so I can pull with my hand, rather than a finger.

Its not so much the ringpull as being the problem as the reaction force
of the other hand holding the rim of the tin down ,with fingers only a
few mm away from a very sharpedge, all ok if no oil around and the can
does not slip out of tour grip and then a horrible slicing action of
that edge
