When Superman is not busy saving Lois Lane and Metropolis from daily catastrophe, he’s working hard at the Daily Planet office as his alter ego (spoiler alert!) Clark Kent. When Clark needs to open a letter, he probably uses a Superman Letter Opener, just to keep up the illusion that he is not Superman but instead a mere mortal who can’t open a letter with his bare hands (when in fact he doesn’t need to open it at all since he can see right through the envelope with x-ray vision). For this office product, the Man of Steel is more like a man of pewter holding a steel blade. Close enough. Measures 9″ long.
