I recently started doing this with the lob wedge with what i think are slight adjustments to the why phil mickelson describes it…the face slightly hooded swinging slightly out and up to down n across, i almost just drop the toe into the ground… and while i may misjudge the distance it really dramatically reduced the amount of fat chips and thin chips of which i used to have a lot of and has been working for a couple weeks now and my theory is the toe digs in and the heel kind slides under on slight mis swings and adds forgiveness to the shot. But the thing is….i don't know why its working so well and id like to have some kinda thought as to why its working so well for me, i had been struggling w chipping for years before i randomly ran into this tip online lol.
