I never understood why no one tried to steel or implant Kimimaro bone techniques, while nearly everyone focus on the sharingan. I mean Kimimaro bone jutsu are variation of Kaguya bone jutsu minus the decintegrating part.
The only shinobi that can use the bone jutsu is Kabuto but not to the same degree like Kimimaro like hardening his body.
Hashirama DNA some try to steel and use as their own but the risk is too great, like shown with Danzo going out of control.
