Wield weapon as a light weapon

[Cheiromancer]

I think +1 is a bit too good. A shortsword that looks and deals damage like a longsword is, more or less, a shortsword that deals another point of damage, on average, and +1 average damage is too weak for a +1 enhancement.

I'd price it at a flat increase, probably somewhere like +4000 gp.

It's not just the damage, it's being able to use it while grappling, or in tight corners. I think +1 is spot on.

The sunblade lets a bastard sword function as a short sword, so that's a bigger increase. Further, it compacts feats -- short sword and bastard sword feats are both effective.

I think +1 is fair.
