Soul Solid

The Soul Solid is the weapon Brook uses after the two years of training before meeting up with the other Straw Hat Pirates.

Appearance
Its appearance is almost identical to his former sword. In fact, it is nothing but another cane sword with no distinct new features compared to his old sword.

Abilities
If it weren't because the owner of this weapon is Brook, it wouldn't be special. The name of this swords comes from the fact that Brook is able to channel his own soul through and out of the blade, enhancing its power. With the energy of his soul, this sword can bring the very cold of the underworld and freeze everything it touches, making it a highly powerful weapon in Brook's hands.
