To be more specific, I'm referring to an Archaic Period dory that would be used by Phalanx and the upkeep done regularly.
They have an iron leaf-shaped spear head (seen it referred to as an aichme) as well as another point made of bronze as a counterweight on the other end, but for this question, we are just curious on the aichme.
Regardless of the point itself, we're curious on the sides of the leaf and whether they would be sharp enough to use as a cutting weapon, similar to a halberd perhaps.
I'm new to r/AskHistorians so if I'm in the wrong place or this is a wrong question; just let me know.
Thank you.
The words aichmê and doru are synonyms. They both mean "spear". They are not technical terms referring to particular types of spears; the Greeks were rarely very specific in their use of military terms, at least until the Hellenistic period.
As for these weapons, they would of course be sharpened, or else they would not be of much use in a fight. Our sources suggest that they would often only be sharpened immediately before battle; this was probably to make sure an edge wouldn't be lost before it was really needed. The Spartans famously sharpened and polished their weapons on command just before battle, as well as combing their long hair. Others also waited till the last moment:
When he gave them the last order to make ready, saying that there would be a battle, the horsemen eagerly whitened their helmets at his command, the hoplites of the Arkadians painted clubs on their shields as though they were Thebans, and all alike sharpened their spears and daggers and burnished their shields.
-- Xenophon, Hellenika 7.5.20
That said, even a sharpened spearhead would not be very easy to use as a slashing weapon. To my knowledge, there is no pictorial evidence of a hoplite using a broken spear, though it is often suggested that they would. Instead, they would use their short swords for close fighting or desperate defence.
