People talk about them, just not often. Mainly because everybody knows what they are. Extremely well made, high end, and expensive. Basically jewelry, as others have said, but also functional. The reason they're not discussed much, even though they're highly respected, discussion here usually orients around using knives and the various materials in such user knives, rather than which knife goes best with your Patek watch and Armani suit. Certainly there are people here that'll spend as much as a WH on a single knife, but for that cost, they usually get a custom, or like in your avatar Colog, high end versions of familiar knives like the Sebenza.
Basically, all you need to know is that if you want one, and can afford it, you won't be disappointed in the quality.
