Got some proto ASD combination wrenches in black oxide a little while back. Ordered them individually in 10-24mm skipping a 20mm and 23mm. Pictured on a Cornwell wrench wrack, the 24mm sits separately in the bottom of my box.
The beveled entrance to the open jaws makes them easier to slip onto a fastener head which came in handy recently when I was spinning a banjo bolt down in a small area.

Compared to an old Proto, 19mm ASD on top, equivalent 3/4" on the bottom. You can see that the new ones are a bit longer and the beam meets the head and box end with a radiused fillet instead of a 90 degree parting line. The beam profile has also changed to be more of a rounded off rectangle than the pointier oval on the old ones.
Besides the ASD feature, the box end has also been redesigned. Rather than the old two-angle design, the valleys are radiused and slightly recessed back from the peaks for off-corner loading. The radius and angle on the chamfer has also been reduced which theoretically provides more contact area on the fastener.
