TOB or Path of War? Either of those make weapon choice not super important. PoW has a defensive based class that may synergize well with using a shield.
Another option, which is maybe more amusing than practical, is to repurpose the Scropion Kama into an appropriate weapon and crank up the unarmed damage, and so you've got a little sword that does tremendous damage. That may be a lot of work to achieve what TOB gives you out of the blocks, though.
And, are you opposed at all to gish types of things? The pic for some reason made me think Psi Warrior.
