The "S" wrench design is optimized for turning square nuts, which were widely used on large machinery and carriages during the 19th and early 20th centuries. But by 1925 the use of square nuts was declining rapidly, and the inclusion of this wrench style in the initial "Superrench" line seems surprising to us.
