I wonder if this can be right.  It seems like it might be a
reanalysis, but of what?  There are no hits on google for "catch
metal toes", let alone the full expression, and my northern Michigan
informant (OK, Leelenau County, not U.P.) has never heard of it or
any reasonable permutation.  Maybe a nonce form?  I guess it worked,
if your informant understood it as a warning.
