Details without flash. Like you can see at the above posted first picture had the blade active rust when I received it, the pitting let by the dark areas is still visible, the bolster area was a challenge to clean, the scarred surface near the tip is not rust pitting, it's either from the original forge finish or from a later straightening from the blade tip!? Any suggestions? The other side has a flat surface.
