Think all knife sharpeners are the same? Think again, the TechEdge professional knife sharpening system by Furi is an easy to use way to restore sharp edges to your kitchen knives.

The system comes complete with three different attachments that sharpen knives through three stages--reshaping, coarse honing, and fine honing. If you have a dull knife, the Edge Restorer uses two tungsten carbide cutters to restore new angles to a rounded edge. The cutters adjust easily for different cutting edge angles and are much faster and more accurate than a stone.

The second phase uses Diamond Fingers Sharpener, a set of six stainless-steel spring fingers that are bonded with 450-grit crushed industrial diamonds. More exact and consistent than a steel, the fingers automatically set correct cutting angles and create a fine micro-serration that is perfect for most kitchen knives.

The third phase uses the Tech Hone Fingers, an attachement similar to the Diamond Fingers but with a coarse striated surface that creates a fine finish.

All three sharpening pieces fit snugly into the Tech Edge base, which has a long handle and a wire safety guard to protect fingers and hands. The base folds flat to fit into the included snap-shut carrying along with all the other parts of the system for tidy transport. Furi also includes a 25-year warranty.
