Brookstone was a retailer that advertised "Hard to find tools."  I still have several purchased in the 1970s.  A set of carving chisels identical in every respect except color to the Millers Falls set.  A set of needle files I used to duplicate a small key only yesterday.  And a pair of offset, ratcheting screwdrivers.  

Sadly, they moved into the artsy fartsy merchandise and went under.
