Answer:
Brutus means that in all his life he he didn't know one man who wasn't true to him
Step-by-step explanation:
In Shakespeare's "The Tragedy of Julius Caesar." Brutus asks his men, Cl*tus, Dardanius and Volumnius to kill him, but refuse to commit the deed. As a result, Brutus feels pleased to know that all the men he has met have been truthful to him. Finally, he asks Strato to hold his swords while he runs to it. Thus, Strato accepts and gives him a handshake first, as a sign of his respect and admiration.
