Uh-huh, and what are you gonna do with a spear? Wiggle your wooden haft at the Blood Knight until he snaps it like a twig and cleaves you in twain, groin-first? You're literally admitting yourself that swords are more suited to such foes. And this is besides the fact that by the time you're fighting such creatures you should have had your weapons enchanted to bypass that issue altogether.
Putting that aside, what are the most common causes of adventurer death? That's right, wolves and goblins. Neither of which need any "impact force" to slay, and both of which hunt in packs. You think that shitheel rogue you picked up in the tavern's not gonna break formation at the first sight of a falling gold pouch? You think that level 15 wizard who's only tagging along for the alchemical ingredients is gonna give two shits about watching your back while you fight 5 to 1? He'll probably burn YOU and your shitty little spear to a crisp just to get to the enemies in front. Adventuring means fighting outnumbered and without support, that means a SWORD. Not a little knife on a stick that can only handle one foe at a time.
Also, have fun rummaging about in your bag of holding for your knife on a stick while beset on all sides by ravenous ghouls. I'm sure they'll wait for you to get it out before they feast on your entrails, they're so renowned for their manners after all.
Actual fairy tales. It's not even worth arguing with you, I doubt you're even an adventurer. You're probably just some town guard too dumb to learn a crafting skill or join a guild, standing around all day wagging your finger at the level 1s scrounging up spare change out of random barrels in town. I'm real happy for you that you and your fellow village idiots banded together to clear some innkeep's cellar of (regular size) rats last week but your experience sticking small rodents doesn't carry over to real adventuring.
