Jura can
resist piercing damage, we see this in the fight with Boruto. Boruto uses the Kusanagi multiple times and only manages to cut him after using FTG to
get behind him. We
then see them trade, Boruto using the Kusanagi, a weapon renown within the Naruto verse for it's
ridiculous sharpness +
The Uchiha Flowing Blade : Hagoromo to further increase said sharpness, is incapable of piercing Jura consistently.
The staff itself isn't necessarily sharp, and the scans sent in the previous message shows that V1 Kawaki can go toe to toe with Jura just using the staff, and can damage him heavily after using the "sharp end".
So it should likely be Karma Beam > Rods > Staff (pointy end) >~ Jura ~ Kawaki (Using rounded side of the staff)
