These knives are incredibly well made, as expected from Zwilling. They're perfectly balanced, the handle material is comfortable and easy to care for, and the edges are super sharp. The easy half-bolster makes it simple to use a professional pinch-grip when chopping, something the Pro S series doesn't do as well. These are a true professional's choice. Also, with all knives, the real test isn't how sharp they are at first (everything will be, even cheap ones) but how long they hold that edge and how easy it is to put it back. Time will tell on that, but I know this allow has a reputation for being great in both cases. [This review was collected as part of a promotion.]
