The first advantage is that the cutting edge is consistent in it's force against the material being cut from the heel to the tip. As opposed to a blade shape with a "belly" that reduced the force (angle of attack) that changes towards the tip. Cutting materials like rope, the straight edge will prevent the rope from "rolling" off the blade.
Maybe not totally on topic, but folks, whoever loves the specific wharncliff advantage Sal mentions above, but still also wants some belly on a knife:
Have a look at the Stretch, especially the discontinued Stretch 1.
The Stretch is the only NON wharnie Spyderco I currently own that has a pretty long, totally straight section of edge (about 4cm = 1.6") before the belly starts to rise
All other Spydies I own (even the Endura, though just very subtle) actually have a more or less slight curve in the edge, pretty much starting from the heel of the blade.
So: With the first 1.6" part of the Stretch blade one can do real "wharnie style" cuts on rope and the like.
The long perfectly straight section is also noticeable when for example whittling wood, especially when compared to something like a Manix.
Top three going by pocket-time: Endura 4 in VG 10/Micarta-scales; Stretch 1 in VG 10; Endura 4 in HAP 40
