Lol , what do you think? Cut the head off a nail so you can fit the shaft of the nail in the tool. . Round off the tip of the nail with a file, bench grinder, a (locally sourced)rock, sand paper, your sidewalk, basement floor or anything decently hard. It’ll round off fairly easily.
The nail I found in my basement was pretty soft and rounded off the tip of it in like 10 seconds.
