Shaving vs Push cutting?

Ok I have a weird problem.
I have a buck vantage pro, and my dad has a kershaw blur rescue (he took it to a grinder and added a tip :( )
I sharpened them both up and compared. The blur will save my arm hair like a razer, but it won't push cut paper?
My vantage pro will push cut paper like butter but won't save as easily as the kershaw?
I'm sharpening at 15 degrees on my lansky.
 
The Vantage Pro is a relatively thin hollow grind. It meets less resistance push-cutting through paper.

What about the shaving then?

Shaving only depends on the first 0.2 mm of the blade's edge. You can shave with an axe. Push cutting through material depends on the entire cross section of the blade. An axe will be poor at push-cutting through paper even if it is sharp, because of all that metal behind it. Does it make sense?

now it does.
Since hair so thin it won't use the blade just the very edge. While paper the edge must go in but the blade must be able to follow through.

Yep... that's why I like the Vantage Pro so much. You can get it quite sharp too by the way.
