Answer

I'd like to say I am titanium.
I did a project in 8th grade science class
and I was assigned the protons and electrons of titanium.

I probably failed,
because I was drawing 
or writing in the back of class.

More likely,
I am copper,
cold, carrying and just.

Or aluminum,
all purpose,
extremely recyclable, right?

Hammers and axes aren't tools of destruction.
Hammers build homes and poems.
Axes chop wood to build fires.

Arrows, now that's another story.
You're the quiver and the quill.
Does this answer your question?
