In Defenders of the Faith there were spells like Sword Stream and Knife (?) Stream. These are great spells for the domain list.
I created a similar domain for a group of clerics that worshipped "The Way of the Sword". Essentially they were clerics of a conceptual ideal as opposed to a deity.
The Domain Power was martial proficiency in all swords. No Focus, No Specialisation, just the ability to use all swords.
In addition, they were banned from taking the War domain due to its inherent violation of a focus on perfection. Yes they could cut a man down without blinking, but they never sought to do so.
Since I don't have my notes with me, some of this is from memory:
Spells included: magic weapon, greater magic weapon, weapon of the deity, blade barrier, sword stream, knife stream, and tensers transformation.
Flavour of this sect: they never used magical swords or buffs (spells or items) since it didn't make them truly "at one" with their blades.
Originally I wanted to make a prestige class based around the "best" of the sect. This would give them access to Weapon Specialisation and other "manga-like" abilities but never got around to it.
