Straightening bladed spokes I have a wheel set with bladed spokes and they regularly become twisted such that the spokes are no longer lined up with their thin side to the wind, as indented.  They twist so that the broad side of the spoke is breaking the wind instead.  

This has to be a pretty common problem and I was wondering if there is a good way to straighten the blades so that they are aligned properly?  I usually go at it in a pretty crude manner, taking a leatherman or some other multitool and carefully grabbing and turning them straight.  The problem is that the tool is usually too big to fit properly in between the spokes and there isn't enough room to twist the spoke back completely straight.  It's especially difficult when there is a lot of tension on the spoke.

Are there any methods or makeshift tools that one can use to straighten bladed spokes without the risk of damaging them?
I had the same issue and ended up taking a piece of very hardened plastic and melting a thin channel out of it the same width as the thin side of the spokes.  In this manner, I could hold the blade in place while I was truing the wheel.  I never had problems with them twisting when I wasn't cranking on the nipples, however.

To be clear, I heated and melted the channel in the plastic with an unused spoke (extra from building the wheel) and then threw that spoke away.  I would never recommend heating a spoke currently in, or intended to eventually be used in a wheel.
