As stylish as blades are, they lack any distinct advantages over blunt weapons in most cases.

Skeleton Hoarde? Blades aren't going to do much but cudgel will sunder them with ease.
Big guy made of rocks? Blades will make a delightful tink noise, blunt weapons will pulverise them.
Cyborg Rebellion? Blades won't be much help against the robotic parts. Blunt weapons will grind them to dust.
Pirates? They'll parry and riposte any sword attacks. They don't know how to do that when up against a mace.
Big blob of ooze? Poking with a sword will have little effect. Smashing it with a warhammer will have a huge effect.

Blades are more effective against zombies, dragons, everyday people, and carp though.

Anywy my vote goes to the absent option for piercing weapons! Come on, how can you forget those? Spears, Crossbows, Guns, Bows and Daggers are way cooler than your silly Swords, Scythes, Katanas, Warhammers, Maces...
