Hi there, I have this sentence, and I was wondering if the use of the word "fixed" below is correct, and if so, what you think would be a more attractive alternative, if any. Also, in this context, should it be "fixed at" or "fixed on"? English is not my native language, so I sometimes struggle with little stuff like this Thanks! "Don't you say nothing at all, young man." She snapped at him with her raspy voice, pointing her bony finger as if it were a rapier fixed at an adversary.
