What I want is for my target to feel it when I hit them. I hate that it doesnt even cause them to flinch, much more, prevent them from attacking or continuing their attack.

The two handed axe or the claymore were terror weapons, intimidating, yet very inefficient, If you hit you killed, or at least disabled the enemy; if you missed the swordsman ran you trough. The spiked sledgehammer was mainly used to unhorse knights and punch trough plate armor when they were on ground.
Historically *swords* where what we RPG nerds call "short swords" today. A 4-5 ft long sword was used two handed and occasionally one handed, just like we use two handed swords in games. A two handed sword, as large as its wielder, was an open field weapon used to scythe away spear formations to make place for the own cavalry and to unhorse enemy riders. Like most polearms it was useless once the enemy came too close.
