Normally I'd bash it at the bearing & the Ali will fall off. The bronze bearing might break in half too, or bash it again.

Then I bash the contacts & they break apart & the bits are solid copper with insulation stuck in it.

I use a meat cleaver to remove the loops at one end & then pull out the copper wire from it.



Sometimes the insulation is solid & won't let you do that. I burn those off in a fire & the snip the loops & pull them out.
