I have come to the conclusion that the "same old silly questions" are just the nature of the beast and are not ever going to stop.
I just leave them alone because it seems you either can try to be really helpful to an unappreciative audience, or get frustrated and then come off like an elitist dick. Neither option is much fun.
IMHO- If a person isn't willing to make the effort to do some reading on their own, then they sure as hell aren't going to make the effort required to make even a DECENT knife.
It's akin to a person walking into a book-store, looking at a book on the shelf and saying out loud, "I wonder what's in that book?!?!?" without even making the effort to pick it up and glance through the pages.
