When you baton, to do it right, you got to ease up on the handle so that when you hit the spine of the blade, the handle rises up. Then you push down on the handle to reset the knife to a horizontal position. Then you hit the spine of the knife towards the belly and tip and you let the handle rise up again.
It wouldn't matter with INFI very much I'd hazard, but you want to avoid forcing the tension to the mid point of the blade where the tang starts. Let the handle rise and the whole blade takes the shock.
Most folks will be well served by crafting a wedge and then starting the cut with the knife before placing the wedge to baton through. This will avoid knife contact with dirt and rock.
The most important thing is to make sure the edge is straight on there so you aren't beating it sideways and putting lateral stress on edge.
