sorry, wasn't around. I'll rewrite mah post.
Based on PDF related, each weapon has a passive effect that you get just for using it, and an on-hit effect that triggers when you hit someone with it.
Numbers are based on feel. first number for small, second for medium, third for large sized weapon of type. "Large" just means occupies both hands, so Rapier+dagger can work as a "large" light blade. You need to be trained in using these to use their effects.
Shields
>defense actually isn't a bad offense
Passive: Pick a direction. You resist 5/10/15 damage from that direction until the beginning of your next turn
Effect: The target has disadvantage on melee attacks against you/on all melee attacks/on all attacks
Polearms
>keeping your enemies at arm's reach
Passive: Reach +1/2/3
Effect: Slide target 1/2/3 square
Heavy blades
>with great blades come great cleavage
Passive: enemies ending their turn adjacent to you take 5/10/15 damage
Effect: make a secondary attack against 1/2/3 adjacent enemies
Flails
>the good ole' ball and chain
Passive: If you have an enemy grabbed, any attack that misses you instead grazes/hits/crits it.
Effect: The target is grabbed/grabbed and disadvantage on breaking out/grabbed and restrained
Hooks
>in soviet russia, hook bite into you
Passive: your opportunities slow/immobilize/trip enemies until end of turn

Light blade
>butterflies, bees, etc...
Passive: You shift 1/2/3 squares when you shift. If you end in full cover from all enemies, you can try to hide immediately
