A chef's knife and a paring knife are the two most important knives in any kitchen. The hollow edge is crafted with evenly spaced vertical indentations, which create small air pockets between the blade and the food. These small air pockets gently push food off the blade and reduce friction and drag. This knife set includes a WÜSTHOF Classic 6" Hollow Edge Chef's Knife and a WÜSTHOF Classic 3 1/2" Hollow Edge Paring Knife.
