The technique is highly versatile, since with it, the user can slash multiple targets at once, and if they so wish, the damage they inflict can be as fatal or as incapacitating as they like. The actual attack itself, however, is never seen clearly due to the speed implemented. It is usually at this point that the victims start manifesting and feeling the effects of this high-speed attack. It seems to employ elements of iai (instant sword-draw-and-resheath) since it is generally initiated (though not always) with the user moving towards the intended target(s) with an unsheathed blade and walking past them before sheathing it back. Only when a certain amount of time has passed, which is approximate to the time the user walks ten feet away, or three meters ( verses, as the name suggests), does their opponent realize the attack. Hanauta Sancho: Yahazu Giri ( 鼻唄三丁矢筈斬り, Hanauta Sanchō: Yahazu Giri ?, literally meaning 'Three-Verse Humming: Arrow-Notch Slash'): The user slashes an opponent at such a fast pace that it appears that they did not attack at all (in fact, to the casual observer it would look like the user simply walked past the victim).Before the Timeskipīrook using Hanauta Sanchō: Yahazu Giri against Tararan.

Swordsmanshipīrook uses a graceful form of swordsmanship that resembles classical fencing ( フェンシング, Fenshingu ?) and Iaido.

He would utilize this enhanced blade with his graceful swordsmanship. Due to this feature, Brook gave it the epithet of 'Freezing Sword' ( 凍える剣, Kogoeru Ken ?). The energy of his soul brings the 'very cold of the underworld into this world', resulting in the sword being freezing cold.

Additionally, Brook is able to enhance its power by enveloping the blade with his soul using his Devil Fruit ability. The sword is highly sturdy and resilient as it remained untarnished even after being used by Brook for more than fifty years in countless battles before the Longarm Tribe sharpened the sword during the timeskip.
