Two kinds of sarissa?

[Robert Vermaat]

One would also think that more than a single example of one would have been uncovered throughout the ages. If hundreds of thousands of these things were produced (had they been connectors to sarissae), you would think one would show up somewhere else.

Indeed I can say the same for Roman spears, nothing has turned up in the archaeological record. Plia of course have, but only the metal parts. The closest we get to (long) spear shafts is from the Scandinavian bog finds.
