WrightGrip 2.0 wrench set

[SubLGT]

The Williams SuperCombo wrenches are similar to the Wright Grip wrenches in concept (but $80 more for the 18pc set).

Williams describes the box end as "SuperTorque":

SUPERTORQUE® box opening design allows application of higher torque without rounding or deforming hex fastener points. No contact is made at the corners. Instead, wrenching forces are placed on the flat surfaces behind the points.

Strangely, at the Wright website I could not find any similar description of the box end on their wrenches.
But they had this to say about their sockets:

The Wright Drive design distributes contact stress more effectively than any other wrench system. With the stress spread over a larger contact area and away from the corners, Wright Drive improves fastener torque load while decreasing rounding and distortion of the fastener............
(Maximum .057" length of flat contact at engagement under load with [12pt] 5/8" Wright Drive design and SAE Grade 5 fastener.)

They make no mention of "WrightDrive" being used on the box ends of their combination wrenches or box wrenches. I guess we can assume it is being used?
