- Three-stage process: sharpen, hone, and polish with 100% diamond abrasives
- Converts standard 20-degree American/European knives to sharper 15-degree Japanese-style edge

- Expensive — costs more than most chef's knives
- Bulky footprint requires significant counter or cabinet space
- Extensive manual required reading before first use — not intuitive out of the box
