The above really made me laugh. I'm from the Ozarks as well and have had the exact same experience. Tried often to nap chert, including one afternoon stuck sitting by a "braanch" (sound familiar, Bill?). Got several very sharp edges and cuts (including one on my knee that infected a bit), but never succeeded in learning how to do it properly.

I also now carry what I believe is the smallest Swiss Army knife, and have used the tooth pic and tweezers more than the blade. Far cry from the sheath knife that was my pride as a kid.

best, jcp
