Depends on your source material. A pole axe was different from a halberd, which was different from a fouchard-fork, bill-guisarme, guisarme, glaive-guisarme, bill, glaive, fourchard, trident, military fork... and hopefully you get the idea.
Each of them had a separate stat line in 1e and 2e D&D, although you needed a separate chart in a supplemental book to actually tell what they looked like.
