The sewing needle...can't really tell you why I love it so much tho
Depends what the purpose is. Generally it would be Samehada can track, absorb chakra grant regeneration shark mode. My choice though is Hiramekarei it can be used like susanoo and fashion shapes/weapons. It allows greater chakra(form) manipulation the potential is limited really by an individuals chakra or skill.
Hiramekeri would break Perfect Susanoo with confidence.
And you can make chakra contstucks with the weapon and make the Kabutowari or Nuibari.
I think the Hiramekarei is stronger then the Samehada. you know we are going to get more Jutsu reveals for the sword.
I am going to add pics at some point so more people can see the swords.
Versatility wise I'd agree, but the problem is Samehada can eat it's chakra structures. The most potential versatility still exists for Hiramekarei as I've pointed out.
There are underestimating hiramekiri it is the most powerful in my opinion. It can increase in size and power according to confidence. Even though chojuro is shy it has this much power what if wielded by someone like mei or tsunade or raikage or Madara who have extremely great confidence? It will destroy the world.
