"These kitchen knives are crafted from 33-layers of VG-10 damascus"
More likely they have 33 layer 'damascus' cladding over a vg-10 core.
"Because each layer wears at a different rate, it causes a micro serration that’s sharp and long-lasting."
I've yet to see a knife where layered 'damascus' steel forms the edge (and for good reason). This claim is probably nonsense.
"Featuring a strong full-tang construction"
I doubt it, they have traditional Japanese handles and so probably traditional Japanese rat-tail tangs.
Anyway...
For anyone in the US, you can find some of these knives at lower prices here:

PS. You may need to run the above search again to get it to work properly.

This is a recent fad among custom knife makers who just buy damascus/pattern welded stock and thin it down. Some bladesmiths producing such stock will also turn it into knives. Of course quality control is all over the place with this method so no major knife manufacturers have dropped san mai (tri-layered) knives when they use damascus.
Also, Staples? ................................... what?

FriedShoeInteresting. I would have thought that the softer steel in the mix would make for a fairly useless edge (unless you just wanted a thin hacksaw type blade all along!)
The staples link works for me as posted, but on at least one occasion I had to hit the search icon again to get it to show results. It's just a search for "Chroma Haiku Damascus" at staples.com.

FriedShoeBy the way, I still think these particular knives are likely to have a mono-steel core of vg-10. This is what Chroma says about them: "Sumikama provides CHROMA in Japan with unbelievably sharp blades made from 32 layer Damascus an VG-10 core steel with a hardness of HRC 59-60°."

JaggiThe steels used in a damascus billet could easily have no discernible differences, though I have no idea how commonly this is considered. You could for example make a billet out of 1095 and 15N20 which are both excellent steels alone and while the resulting billet will have different wear rates between the two steels, you'd be hard pressed to find a home cook that notices.
I'm just surprised Staples sells kitchen knives...
Mono-steel core is what I was referring to as san mai. This is the traditional Japanese technique of sandwiching high quality steel one either side with cheaper steel.
