Jim,
We have had an interesting discussion on the proper type of screwdriver blade for use in the Super Tiger screws (I think also the OPS engines use these too) . It seems that one should have a blade that fits tight in the slot and has flat sides rather then the normal angle sides on most standard blade screwdrivers. With the flat sides it won't push out the top of the screw slot and damage the screw. I was wondering if you could make this tool available to us?
Best, DennisT
