Going back a few posts;
Don't write off copper nails, they aren't neccesarily pure copper and are hardened in manufacture, anyone having used "copper" sparkless chisels for cutting steel will attest to how hard copper alloys can be.
As an apprentice I did six solid weeks splitting rusted nuts off of salt water heat exchangers in a benzene, toluene and xylene manufacturing plant, it was too dangerous to use anything that could generate a spark, so no grinders, flame torches or steel tools of any kind just me a copper chisel and a copper hammer, and about 500 3/4" high tensile bolt sets, about a year later they banned the use of xylene in permanent marker pens as it was considered to be too poisonous being a known carcinogen, we were producing thousands of litres every day and breathing it for eight to ten hours a day made me so sick that after four days I couldn't work on the fridays, makes me wonder sometimes.

Whatever it is, do it today, Tomorrow may not be an option and regret outlasts fatigue.
