unburnished

Anything unburnished is dull rather than shiny, like the unburnished surface of your grandfather's old pocket watch.

If a metal is dull or matte, not polished to a high shine, it's unburnished. In a fairy tale, a group of ogres might underestimate a knight who shows up on the field with rusty armor and an unburnished sword — until he single-handedly defeats them all. This adjective is formed by adding the prefix un-, meaning "opposite of," to burnished, "polished, glowing, or cleaned to a shine."
