Sharpen Knives Like a Pro From Home

Keep Knives Sharp, Safe, and Ready to Use

Wondering how to keep your knives sharp without replacing them or dropping them off with a professional? The Tupperware Universal Knife Sharpener is a superior solution for keeping your knife blades at their sharpest right at home.

Designed for Straight and Tupperware Serrated Knives

This innovative knife sharpener works on both straight-edge knives and the special serrations of Tupperware serrated knives. (The sharpener features pictograms that identify which slot to use.) Whether you’re slicing tomatoes, cutting crusty bread, or prepping vegetables, you’ll enjoy smoother, more precise cuts.

Built with Safety and Comfort in Mind

When open, a protective shield sits between your hand and the blade, the cover doubles as a hand rest for your comfort, and non-skid feet keep the sharpener steady on your countertop. The rounded, ergonomic shape provides a secure grip and works comfortably for both left- and right-handed users.

Professional Results at Home

The sharpening mechanisms help protect your investment and prolong the life of your knives, as they remove only a minimal amount of steel while dramatically improving sharpness. That means better performance without unnecessary wear.

Easy to Clean & Compact, Easy Storage

Each part can be disassembled for easy cleaning. When not in use, the sharpener folds flat to fit into a kitchen drawer, helping you keep your kitchen neat and organized.
