Figurative use: the direction or target of an attack, criticism, or argument. Often used with verbs like 向ける (direct), 向く (be directed), 交わす (dodge), or そらす (deflect). Sense 3 (force/edge of an argument) is closely related and naturally covered by the same figurative usage.
He directed his attack at me.
The brunt of the criticism is directed at the government.
He directed his criticism at his boss.
The focus of the argument suddenly turned to her.
He deflected the pointed question and changed the subject.
He skillfully dodged the brunt of the criticism.
Rare single-kanji form; 鋒 can also be read きっさき or ほう, so this spelling may be ambiguous.
