Ikkyo, when applied correctly and powerfully, will turn uke heels over head. Unless an "ikkyo breakfall" is taken, this will cause uke's face to either get crunched into his or her knee or, perhaps worse, right into the ground...

Ikkyo (or oshitaoshi as we call it) will often put uke's head exactly where the feet were in an instant depending on the kuzushi. Ukemi must be natural and relaxed!
Some years ago a fellow attacked with a high level of force and speed during randori and reacted so strongly to my oshitaoshi that his head and feet switched places and on the way down his chin connected with his own knee producing an unconscious uke!
He was okay, but said that he couldn't remember what the experience felt like.
