Katarina x Katarina
One Draven can pick axes of another Draven. Why in the same way can not Katarina?
This is logical: she sees the blade of another Katarina on the battlefield and uses it.

If Kat could, you'd never want to use them, since they can be used against you. For Draven to use the axe of another Draven requires strong positioning and gameplay, and often Flash. They also can't blink to those axes.
Because Draven can't dash to his axes?
