They don't sound like they are cost-effective for most types of use, IMO. If you really don't like sharpening knives then I guess they would have some appeal, and they will be trendy among those who like expensive knives and designer steels, but my guess is that they will have a limited following for the time being, and the price will lean them towards collectors rather than users. The knife market has seen so many new super-alloys emerge over the last decade or so, that the technology is well ahead of the needs of the average user, IMO.
