How could I achieve a block system for a melee game (line trace)?

Hello guys!
So I am currently making a melee game (similar to chivalry medieval warfare) and i already nailed down the attack system with line traces that follow the sword. But a good melee game needs a complete parade system with blocking in it.The problem is I have no idea how i could achieve the blocking system.Maybe when line traces collide together the game could tell not to inflict damage to the player?
Any kind of help is appreciated ! :slight_smile:
Thanks in advance and here is a picture of the attack line trace attack system :slight_smile:
