Cleave (also known as Spincut in the SNES/PS version) is the fourth Tech learned by Crono in Chrono Trigger. It deals physical damage to a single enemy, and it consumes 4 MP.
Animation
Crono leaps high into the air, leaving a shadowy after-image. He then brings his sword hard down upon the enemy.
Enemy Tech
Cleave is also an enemy Tech used by Slash and Steel Shade. Slash only use it when he is equipped with the Slasher.
Etymology
The verb "To cleave" essentially means to split/cut something with a sharp instrument, which is what Crono does here with his katana.
