There's a couple of unofficial feats from the Netbook of Feats (
http://datadeco.com/nbofeats/)
ARMED FLURRY OF BLOWS [Martial Style]
You can attack with a flurry of blows with any weapon that you are proficient in.
Prerequisite: Monk level 3rd
Benefit: This feat expands on your Flurry of Blows ability, allowing you to flurry with any weapon that you are proficient in.
Normal: Flurry of Blows can normally only be used in unarmed combat or when armed with a kama, nunchaku or siangham.
FLURRY OF BLADES [General, Fighter]
You can strike exceptionally fast with light weapons.
Prerequisite: Weapon Finesse, Weapon Focus (with Weapon), Base attack bonus +3, Dex 13
Benefit: Choose one weapon that you have Weapon Focus and Weapon Finesse for. When unencumbered, in light armor or less, and wielding this type of weapon, you may make one extra attack per round. The attack is at your highest base attack bonus, but each attack (the extra one and all the normal ones) suffer a -2 penalty. You must use the full attack action. This feat does not stack with other feats/abilities that grant extra attacks, such as Flurry of Blows, two weapon use, double weapons, or creatures that make multiple attacks. It does stack with the iterative attacks of a character with high base attack bonus.
Notes: This is a fencing technique, and fits well in a renaissance-style game.
