Out of all the cliches that I'd say are actually bad in this manga, it'd be the "there's a voice only I can hear and people think I am talking to myself" gag.
The sword told the MC he can talk to it in his mind, yet he constantly keeps yelling outloud and creates needless misunderstandings. What a bizarre choice it is to intentionally create a gag, turn it into a problem, give it a solution, and then completely ignore it.
Other than that, pretty basic story. Does its job. I'm surprised there're people who are so mad about the censorbars.

As I wrote up there in my comment, if anything, the truly trashy aspect of this manga is the shitty comedy gag of yelling to an inside-voice. Other than that, I cannot possibly see how this basic arse story is ""bad"", as; it is actively unpleasant to read.
You want horrible, shitty, beyond redemption writing?
Go read this..
