Designed for the aspiring hobby chef, the Professional S series provides the excellence expected from Zwilling J.A. Henckels, the upscale partner of Henckels International. The 5-inch santoku knife starts with the traditional look of the three-rivet handle and adds a hollow-edged blade that's practically a necessity these days in Asian cooking. The hollows create air pockets that allow thin slices to fall away without sticking. Professional S blades are superbly constructed of premium high-carbon, no-stain steel that is Friodur ice-hardened for increased ability to hold an edge and take sharpening. The classically styled handles feature the strength of a full tang and triple rivets, while the enhanced bolster adds to the beautiful balance. Henckels recommends washing and drying all fine knives immediately after use. Made in Germany, the knife comes with a lifetime warranty.
