Heres one We made using the first million++ layer billet that Randy Jr forged. Its got Koa and mammoth ivory handle.

Thanks for looking.
Randy

At about 50 thousand layers we added 8 extra layers which gave us some visible pattern after reaching a million!! :)
 
We did a WIP showing the forging process on this billet on KKF and KD if ya want to search for it its out there!! :)
 
Ah thanks! Any idea of the amount of carbon migration after having the billet in the forge for so long? What hardness did you end up with?

I also love the koa!
 
The way We develop layers on this is probably different then you might be thinking. It was really not in the forge as long as you might think. Only a couple more weld heats then most other billets we forge.

RC 60. after HT and Temper.

Im not a Metallurgist I am a knife maker. So I cant speak to that carbon migration question. Maybe someone with more knowledge then I can state there opinion on that. What I can say is that the finished steel is perfectly suited to be used as a knife.

Have a great day and God Bless

Ok. The amount of carbon loss is really difficult to find out, I asked it because it was something I was worrying about regarding the million layers.

Have a great day!
 
Van I apreciate the question, and did not mean to come off rude or anything. So far we have had great results with this mix. And actually made another billt without any added layers. Its very hard to see the layers in that bar. :) But the finished steel is still quite beautiful and unique.

Have you done any forge welding? or experienced problems with your damascus blades due to carbon loss?
 
Thanks guys. Nope we dont do the typical fold over. If you look over at KKF forum or at KD forum. I did a Work In Progress that describes how we got to over one million layers. :)
 
That's such an interesting idea, adding more layers at 50k! D'oh, why does it make so much sense now??!
 
Yes I've done a lot of forgewelding, and have had no problems so far due to carbon loss. I do always keep some extra material left right before the edge, and only start grinding that away after HT. I saw an graphic showing carbon loss in mm depth/hour (for O2), and that was quite terrifying. But in reality I have found no problems so far, still enough carbon left to achieve 62+ HRc. I'm happy that at so many layers you guys are still able to reach high hardness.

I hope everything goes well with your JR's new billet! Good luck!
 
Thanks for the comments. :)

The specs for this one are OAL 15 3/8”
Blade is 10”

Van. thats good to know. Thanks much for the question and info and sharing your experience.
