it's very hard on the edge of a
pocket knife to clean nails. you should
use a wire brush. or better yet, keep
your nails out of the weather and they
won't rust, negating the need for cleaning
them. i usually use nails as needed
rust or not. a generous-sized box of
nails can be purchased very reasonably
at most hardware stores and home
improvement centers. if not properly
driven into place, nails will absolutely
poke your pigs in addition to any other
livestock you may have in an enclosure.
i am also the product of a mixed marriage.
my father had black hair, and my mother
had brown hair. i've never admitted
this publicly.
