"The pen is the sword of the artist / Wield it with courage and faith" and "Producing a child / Through the love of pen and paper" The metaphor of a pen and a sword is really meaningful and the thought of how a weapon like a sword, powerful but only used best when the wielder is skillful, would compare to a pen, which similarly bends to the will of a writer.
Examples of anthropomorphism in the poem give what is easily discarded as mundane writing, human characteristics. It gives life and motion the ink, the pen, and the paper, giving it a story behind the words. Words such as "humble", "bold", "merciless", etc. does a great job in humanizing these objects.
The metaphors and personification in this poem is really nice and well thought of. I would suggest proofreading it for simple grammar mistakes though. Great job!
