Possibly because of the extra AC wielding a scizore offers and its resistance to disarming is the real reason I'm looking at this pairing, but it still seems solid. Certainly I'm enjoying the "one handed" rp appearance of the idea.
Going full arcanist is a possibility, but I also like how well it synergizes with eldritch knight possibilities. But if we do go EK, we still need proficiency with all martial weapons, so we'll need a level in the appropriate class. Fighter is the classic choice, but is it possible to improve on that?
For example, why not a dip into Bloodrager? For a primary caster with a single Bloodrager level, the Arcane, Celestial, and Elemental/Infernal bloodlines look interesting. Swashbuckler would be possible, too. Yes, you don't get the same number of crits as you would with a rapier, but the scizore is a one-handed piercing weapon.
I figure the dip class should be full-BAB, so I haven't considered options like skald or battle oracle, but those would also open up interesting options, wouldn't they?
What might you consider?
