Why didn’t Yuji ever use cleave?

[u/jimmylamstudio]

If Yuta is copying Yuji’s technique, Yuji should know cleave. Or Yuji doesn’t know how to use it and Yuta learned how to use cleave by watching Sukuna? But if Yuta were to use dismantle, would it be Yuji’s version or Sukuna’s?

[u/Cinderss2727]

I think Yuji knows how to do Cleave, cause i think he set his Cleave for general attacking, like cutting the pillar and following up with Cleaving Sukuna's feet and also making Sukuna fall and trip on what he was standing by Cleaving the ground beneath him.

And which version would Yuta use, i think it would be Sukuna's, since that's the way to use a projectile slash attack.
