Professional Sharpening for Zwilling Blades

Founded in 1731 in Solingen, Germany, Zwilling has set the global standard for knife quality and innovation. Our sharpening mirrors that same tradition of precise angles, consistent bevels, and hand inspection for every edge. Each knife is returned sharper, safer, and ready for food prep performance.

One thing worth knowing about full-bolster Zwilling knives: over time and with repeated sharpening, the heel of the blade recedes while the bolster doesn't, leaving a gap that can interrupt a full cutting stroke near the handle. Pull-through sharpeners can't address this. Professional sharpening includes attention to the bolster area where needed, keeping the full blade length usable.

Have Henckels International knives? Those are a related but separate line — same kit works for both. See our Henckels sharpening page for details.
