Know your file

Good advice, mostly, but I take issue with this:

"4. The blade of a file has been hardened to such an extent that it can be broken easily by tapping it on a vise or bench..."

Come on. Files aren't as brittle as glass. If they were, a file wouldn't survive a firm, forceful stroke over a piece of work.

The more I see of technical 'literature', the more I'm flabbergasted by the amount of half-truths, lame orthodoxies and outright hogwash contained therein.
