What's great about this system is that you can put any kind of knife (as long bread knife, short, metal or ceramic) and it contains a dozen! blades and spikes are protected (important for ceramics) and you avoid accidental contact. However there is a small drawback is that you do not see the blade therefore must be classified by size or remember the inning. He has very solid but be careful not to hit the corners. 4 rubber pads and weight ensures high stability (for the move must be raised). Some paint smudge on one edge down, so not perfect finish but does not compromise aesthetics nice, black matt color going with most knife handle. By cons attention fingers easily leave traces. Personally I would have liked to see a more round model with less darêtes ...
