One of Zwilling's most popular block. This all black block looks elegant and contemporary in today's open concept kitchens. The 16 slots provide space for a good variety of knives and 6 slots for steak knives, or a collection of paring knives. A wider slot can accommodate knives that are designed to be wider (6" wide chef's) or have a pronounced arc (rocking santoku). Slots for honing steel and scissors take care of all types of cutlery.
