Mechanical Damascus Koumya Blade

[francantolin]

Hello all ,

I don't even see any real pattern,
on the pictures you show us anyway
For be sure, you ''just have'' to sand it and etch it

Exactly what I've stated in up! Thank you that you don't let me alone!

No other member here in the forum can say that we don't see any lamination on this blade?? Really??

Sorry for my late response, in my opinion it is indeed not damascus but as you said it looks like the structure of hot steel cooled in water or oil. Try if you can bend the blade a little, does it come back straight, steel, does it stand crooked, iron.

Thank you Marc!
My intention is not to make Rob's koummya bad, but to make it clear that what we see here is in no way a lamination in any way.

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.

Didn't look like lamination to me.

I didn't wish to dogpile onto a previous post.
