But its not, slashing someone with an edged spear would do damage. A quick swipe to an unarmored abdomen could easily spill guts. hitting someone with a stick wont however. I dont see why your so hung up on slashing though when you could thrust?
I'm not getting hung up on anything, I made a comment about a singular aspect of the weapon. Frankly I think people need to differentiate between spears, pole axes, Halberds etc etc.
All vastly different weapons.
A spear is a sharp stick.
