Help on homebrewed concept plz

[Sir cryosin]

Ok so I want a fighter archtype that focus on two weapon fighting. So can I get ideas for abilities for this concept.

[RakiReborn]

Rend is one i used for a barbarian path i made: one additional weapon die of damage if you hit with both a main and your off hand attack.

I made a two-weapon fighting prestige class a while back.

Honestly the base fighter seems to support this already, just grab the two-weapon fighting style and the feat and use any of the archetypes.
