Wera, the quality German tool maker, are making a heavy metal tool kit for the Wacken festival.  So it looks like you can now fix the Scurion with the Scorpions playing at 11.

It does look quite good, if a little expensive (?50+ for a few screwdrivers when you add postage).  I've a few items of Wera kit and it is really nice, and their precision bits are well engineered. 

Shame I couldn't make the event as the Sisters and The Damned are playing amongst others.
