Looking at it, i'd probably have the Saigham be a 1d8, x3, Range 30ft weapon, or a 1d8, 19/x3, range 10ft weapon.

The sai, heck, why not keep it as it is and just go with the Elektra-ness of it all.

I only really know about saigham because they're about the only martial arts weapons [aside from dark judge brushes, which are basically the same thing] that i can wield in pairs without hurting myself... Thinking about it, I kinda suck at martial arts
