Out of curiosity, are katars not meant to be affected by weapon finesse? Playing a rogue who has weapon finesse, I was surprised to find that his katar did not benefit from the feat. As a smaller weapon, it would make sense for these weapons to be finesseable. I would also thank the sais, tofans, bak-kauns (claw weapons) and other similar weapons would as well. Maybe it has something to do with them being CEP weapons?
