Interesting picture Doc Drew.

By 'stretched' are you looking at the roughly 45* dark streaks in the light colored band? Maybe I'm seeing it wrong, but that may not be signs of the burst as it does not seem to cross into the dark colored band. Also, those specs you showed earlier had a very similar strength of wrought and low carbon steel. Again, I'm probably seeing it wrong.

Also, maybe of note, if that is a depiction of steel grain in the darker colored band, it seems that the nitol etch is darkening more than just the grain boundries.

Back a few years ago, was there the conclusion that the dark globules might have been carbon? Just wondering.

Thanks for the topic guys.
