I use a machete as one tool to help with gardening. Hard to keep it sharp, constantly sharpening it, so you are probably right. I suppose swordsmen plunged their blade into flesh with the sharp point to cause the most harm. I have an antique Japanese sword but have never used it against a living creature, so this is of interest to me (in case the Obummer zombies run wild soon).
Sharp blades are also useless against armour.
Swords were used to batter opponents into submission, until they were too weak to fight, then they were either run through or hacked until they died from a loss of blood.
And my mom told me that Dungeons and Dragons was an unproductive hobby. :)
