Please pardon the new kid on the block for dragging up old stuff, but quite a while back, there was a lively discussion about period sharpening stones.
In his wonderful and detailed journal, Zenas Leonard reported that trappers in the Rocky Mountains collected petrified wood to use as whetstones in 1833. This naturally led me to a deranged obsession to learn more. Eventually, I stumbled upon a large deposit of this material in my wanderings and gathered several pieces. I'm no rockhound, so have no idea whether or not this is common, but in the case of this particular deposit, the pieces had naturally and quite obligingly fractured themselves into nearly perfect, flat-faced rectangles. No further treatment or shaping required. The question, of course, is how does it perform? Again, I have no idea how much this stuff may vary in texture, but my samples work almost exactly like fine Arkansas stones I've owned in the past. Being so fine-grained, I wouldn't want to have to remove serious metal with these stones, but shouldn't need to do that anyway. After several years of use, there's no apparent wear.
It turns out that this may have been a more common practice than I was aware of, at least in the West. Here's a Cheyenne petrified wood whetstone, circa 1870:
I realize that this is all coming from a period later than most folks here are focused on, but for historical context, it's worth noting that Agricola mentioned in the 5th century that petrified wood whetstones were quite popular in Bohemia (any Bohemian longhunters out there?).
Finally, I can't leave the subject without mentioning my favorite quote on it. Describing trappers' gear in 1846, George Frederick Ruxton wrote: “Round the waist is a belt, in which is stuck a large butcher knife in a sheath of buffalo hide, made fast to the belt by a chain or guard of steel, which also supports a little buckskin case containing a whetstone.” A few other contemporary writers made very similar observations. Note that the knife sheath “is stuck” in the belt, as opposed to “attached to”.
Anyway, here's my interpretation of this description:
And here's my “little buckskin case” and whetstone:
