Just tried it, and it works!. Amazon's Choice, the "World's Best" is not printed on the device, but it well could be :)
My cheapo, 3-slot, noname one broke to pieces week ago.

absolute rip off. unless you set some special value to the wood or the aesthetic sense of the set, but from a knife perspective, i'd never buy that. it's literally just stainless steel, no special type of compound metal used at all, no real special techniques used in the construction of the knives.
check out damascus knives and knives with special harder cores surrounding by softer metals. 100x prettier, cut better, retain edge for longer, etc.
