(quote) "The only dumb question is the one not asked." (Al Einstein) While whittlin' a pointy end on a stick filled with graphite, I started to question. 1) Graphite is an excellent dry lube. "Everyone" (allegedly) knows that. 2) Mechanical pencil "lead" is graphite, easy to find, inexpensive, and easy to crush. While it would be a major P.I.A. to work it into the joints of knives that have pinned construction, for example, would or does graphite powder make a poor, or fair, or good, or excellent, semi-permanent non-stick (possibly and probably messy) knife lube?
