Riddle poem

A riddle in a poem, can you find the answer?

Treat me gentle

And I’m your everyday utility

Treat me rough

And I cut as a knife

I have no arms, legs nor eyes

Yet I can show to you

The riddles in your mind

I have no color

But I am all colors at once

I reflect light

And absorb darkness

Light as a feather

Made of substance strong as stone

I am the beginning of creation
