Tuning Lever Design

[WillSmith.AllenTX]

Please explain to this beginner why tuning levers are not configured to 
pull at a right angle to the pin. It seems to me that the angled design 
just creates a lot of unnecessary pin gymnastics. All that's needed for 
a right angle twist is a longer socket on the handle.
 
Other mechanical fasteners are attacked at 90 degrees...why not tuning pins?

Awaiting your enlightenment.
