Wusthof Classic Ikon knives have some very distinct and highly regarded design innovations. First, the bolster on the Cook's Knife has been modified for ease of sharpening. There is a steel end cap (referred to as a second, or double bolster) that assists in balance and aesthetics. The POM handle has a unique humpback design that snugs nicely into the palm creating a very firm and comfortable grip. Perfect distal tapering and laser guided sharpening techniques are a result of precise German engineering and robot-assisted construction. The steel is tempered to a Rockwell hardness of 58 that is easily maintained with use of a fine-cut honing rod. Wusthof remains a family owned and operated company after 200 years. Manufactured in Solingen, German, these knives come with a full lifetime warranty.
