I'm in a need of a bit of help concerning Cogswell's poem "Circular Saws." I need to find 3 literary devices, but I'm having trouble. I thought maybe the circular saws were used as a metaphor for "anything hurtful; physical and emotional"...and also that maybe in the third stanza, "...They had ways of disguising themselves" was personification since saws can't disguise themselves, they can only be disguised....but, I'm not the brightest, so I could be wrong. What are some other literary devices you can spot out?
Also, am I right in guessing that the meaning is that being hurt is unavoidable and that we are also hurtful?
Thank you in advance.
