Sketched with a mechanical pencil that seemed sheathed in either silver or steel, not really sure. When you turn the bottom counter clockwise lead emerges from the tip. My grandfather served as an artillery officer in World War 2, it's possible that's how I acquired it. All I know is now and then I reach into a shoe box full of pencils and pens and tonight it turned up.
Well balanced when wielded, though to be honest I'm afraid I disgraced it.
