Main point was, you could make templates like macahuitls where you put teeth to fill one edge for X length, and such.
Yeah, if/when item components go in, the weapon definitions will probably get much more template-ish. I recently saw mention of ancient Parthian cataphracts (heavy cavalry) using lances with bone points, and following up on that, I read that the nearby Sarmatians
used bone points on their arrows. Pausanias says they used bone because they didn't have sufficient access to iron, either by trade or mining. I didn't find any explanation for the Parthian use of bone, although my first guess is that there were geographical factors at work (both peoples inhabited areas of modern-day Iran).
Pausanius also mentions something surprising: lamellar armor made from horse hooves.
Their hoofs they collect, clean, split, and make from them as it were python scales. Whoever has never seen a python must at least have seen a pine-cone still green. He will not be mistaken if he liken the product from the hoof to the segments that are seen on the pine-cone. These pieces they bore and stitch together with the sinews of horses and oxen, and then use them as breastplates that are as handsome and strong as those of the Greeks. For they can withstand blows of missiles and those struck in close combat.
Anyway, bone points are just a more obscure variant of composite weapons, which are ubiquitous. The main form is wooden shafts/handles coupled with stone/metal striking surfaces, but there are also more nuanced variations like
bronze-tipped iron bolts and the built-to-break
Roman javelin.Although you can make a serviceable weapon with only a single material, too.
Bone knives, anyone?
