Abilities
With Whitebeard's immense skills and powers, the bisento was strong enough to clash with Shanks' saber, which caused the clouds to split. Also, the bisento is extremely durable, as it stopped Akainu's magma attack without melting.

Trivia

 * It apears Whitebeard use this weapon for defense rather than for attacking as he has only used it to block the attack's of Shanks, Akainu and John Giant.
