Coarse for dull and damaged knives
3.8 x 2 x 1.6 inches and works amazingly well...
• Fine for polishing the knife and for quick touch-ups for an already sharp knife
• Patented Edge Grip feature allows sharpening on the edge of the table or counter top- prevents the tip of larger knives from dragging over the surface of the counter
• Compact for easy storage
• Non-slip base for added stability and control
After pulling through the knives about 5 times, the knives did indeed get very sharp. For my knives, I pulled them through the "course" side 5-6 times, then through the "fine" side about 4 times. Seemed to work well for me.
This sharpener has made me very happy - it truly works better for me than any of the others I've tried. I hope that other people enjoy this item as much as I do now because I'm giving it to family members!
