It really bothers me that this thing will not stay straight. I cannot remember how many times I have heated this thing, straightened it, and cooled it only to have it revert back to the shape with the packaging bend damage.

So here is the my plan to end this problem once and for all. I have taken great pains to use twist ties to tie this thing to a metal rod until it is straight (nearly perfectly). Tomorrow I will go buy the smallest diameter drill bit I can find and drill a hole through the center along the long axis if the 'saber. I shall then insert a tungsten rod only slightly larger in diameter than the drilled hole (to hold it in place better). Gas Tungsten Arc Welding electrode should do the trick if I can find some of small enough diameter (as this stuff is very heavy).

I would almost bet a week's pay that it will retain it's straightness afterwards.
