I've come across a few builds on here that use the saber in a dex build using weapon finesse but after reading I find that nothing states that the saber is a finessable weapon. so I guess my question is, is their an FAQ or an errata somwere that makes the sawtoothed saber a finesse weapon?
I came across that little bit of info but regardless of that people still seem to be making dex builds with it and using WF, I'm just checking if it's just being house ruled or if and FAQ or Errata exists.
I imagine new builds will be using Swashbucklers 'swashbuckler finesse' - which allows finesse with one handed piercing weapons, and the feat 'slashing grace' which amongst other things allows you to treat a single one-handed slashing weapon as piercing for class abilities.
Unless you're planning to two-weapon fight, there's no difference between a sawtooth saber and a long sword. The primary benefit of the sawtooth sabre is that you can use it in your off hand as if it were a light weapon.
