What surprised me most is not only the hard soft Damascus effect is real, but quite good. The 1095 Nickel is almost up there with ApexUltra in slicing. Something in AEB-L and 304 would be really nice

Great study. Looks like Damascus is still mostly for aesthetics as in every case you could find a mono steel that would be better for a kitchen knife especially if the price is included. You basically get wear resistance somewhat less than the most wear resistant steel of the mix and toughness close to the least tough of the steels in the mix

1095 + nickel is very interesting, but you'd need more testing to see how other attributes are affected. Slicing performance is increased very significantly though.

If one looks for the practical consequences as slicing qualities, I'm curious after the resulting edge stability.

I'm in the process of reading it. Seems really interesting and by a very knowledgeable person (and his dad is super famous)

I would argue that in terms of fame (perhaps notoriety :) ) @Larrin has exceeded his father. His work is widely known amongst even casual knife enthusiasts. He's a great asset to the community for sure.
 
New article regarding Damasteel, one of the forerunners of PM Damascus, the study is also quite interesting, the twisted pattern have retention close or even surpass CPM154, with similar level of toughness. Another interesting thing is at the same hardness RWL34 has better toughness than CPM154, so manufacturing process does matter even the composition are very similar

Interesting article ! But I found the concept of slicing edge retention little too evasive : if we agree that a saw will cut longer than a straight blade, maybe we could mention the difference of quality of the cut. For some application, I am not sure a clean cut is any interesting, but for kitchen knives it's one of the quality sought after.
