Black blade monk weapon?

[Dustyboy]

So my dm is allowing the Arcane Fist from MCA productions,
I'm looking for a good black blade/monk weapon, or a way to easily obtain crusader's flurry without multi-classing.

any ideas?

The Temple Sword?

Though why you'd want to use a weapon when all of your class features seem to be Fist Only confuses me.

Ki Intensifying will take care of that. A Ki Intensifying Temple Sword would probably be best. Alternatively, the Blade of the Sword Saint can be flurried and even counts as a "free hand" for any abilities needing one (ie. Crane Style, Deflect Arrows, etc).
