Mechanical Damascus Koumya Blade

[David]

I believe that Detlef is most probably correct. What you see on this blade is probably caused by the quenching of the blade. Here is a railroad spike that i forged into a dagger that has a similar effect to what we see on your blade and i an 100% positive that my blade is not pattern wielded.

The bright spots on the OP's blade in linear groups remind me of nie or larger martensite crystals that may be seen in Japanese swords. David's attribution to quenching effects is probably correct.

Thank you David! Yes, what we see here is caused by quenching of the blade, exactly what I've meant in post #5.
