Here is an old build that I really enjoyed a few months back. It bears some similarities to a build by Cow Art, albeit those were unintentional, but should be pointed out. His build was there first. It uses anarmed instead of kamas.

The real inspiration for this build was the dark stalker build featured a while back on Bioware Wednesday. I took that concept and modified it to my liking. I wanted to use a monk base as well as still maintaining epic dodge at the time.

End result is you have a character with monk speed and many attacks a round (5 main hand, 2 off hand, 1 flurry of blows and 1 haste). The High AC and epic dodge forces a needed 20 to hit in most 1 on 1 vs. player or monster. The character also has many of the monks abilities with the exception of Ki strike 2 and 3, empty body, and perfect self. The empty body is easily replaced by the assassin improved invisibility.
Max HP is 384, min is 160 (12d8 + 5d6 + 23d6 + 80 from CON + 40 toguhness.
AB with normal kamas is +33/+30/+27/+24/+21 and +33/+30 offhand.
AC is a base of 30 with normal clothes
Saves are Fort: 20 Reflex: 33 Will 21
Finally has a SR of 22 which helps, but isn't great against any caster with quite a few caster levels. Fortunately HIPS and Death attacks help with them, and they get shredded up by the kamas very fast as well.
