It's very difficult to beat a Stanley...they combine pratically the best tool steel with proper heat treatment, to a large diameter triangular shaped handle. The larger diameter handle allows the operator to deliver more torque than with a conventional round handle of smaller diameter. The Stanley screw drivers below are my favorite. When you're garage saling/sailing, these are the ones to watch for (and Winchester, but you don't grind them)

When hollow grinding. quench often and try not to disturb the factory temper...in fact quench too often
