Certainly taste enters into what's knife porn or not.
The blades are wave pattern damascus on a ZDP189 core. ZDP189 is one of the new super steels. In knife steels, there's a tradeoff between the hardness of the metal (how long it holds the edge) and toughness (resistance to chipping, bending, breaking). Most good kitchen knives (Wusthoff/Henkels) have a hardness of about 56. ZDP189 is generally hardened to 65 and still maintains good toughness.
The wood handles are
cocobolo. They are secured with nickel silver pins.
