Just saw this movie today, and I do recommend it. There's quite a bit of flying around, as Chinese movies are famous for, but the story is quite good and it features a lot of fighting...The story is akin to some Shakespearean dramas, and does a good job of showing the wielding of true power.
There is a particular cycle knife/sword a lot like a large bank, or maybe like some versions of the falx. Of course it's used in very weird ways, thrown around and caught back like a boomerang, but nice anyway. I have many many misgivings about the types of warfare depicted but I'll put that down to artistic license
There's also some interesting pole-arm fights, but somehow I doubt these were ever used in close quarter combat. Magnificent demonstration of armour, but again, I somehow doubt these were 10th century styles.
