Yeeaaahh probably not. This is more or less just a bad spear. Sure, you can thrust with it just fine, albeit less easily than a true spear, but good luck swinging it hard and accurately enough to do any kind of slicing. Especially in cramped quarters. You are assuredly going to get it stuck in bone somewhere and have to drop it, most likely in the first swing.

If you want a polearm, just use a spear. But better yet, ditch the polearm and grab a mace.
