The SHARPI Butterfly sharpener delivers professional-grade diamond sharpening in a compact, foldable design. Two diamond surfaces 360 grit for aggressive reshaping and 600 grit for refined finishing restore a razor edge to pocket knives, fishing knives, garden shears, and outdoor tools.
Weighing just 80 g and folding to 125 × 30 × 15 mm, it slips into a pocket or pack with ease. The electroplated diamond coating ensures consistent performance for over 6,000 uses, making it a durable companion for kitchen, workshop, and field.
Diamond Sharpening in a Pocket
The Butterfly design means the diamond plates are protected when closed, and open into a stable sharpening surface when you need them. With two diamond grits 360 for fast edge restoration and 600 for finishing you get a proper two-stage sharpening process in something that folds smaller than a pen.
Diamond abrasives cut faster and last longer than ceramic or carbide. The 360 grit moves through dull metal quickly, and the 600 grit cleans up and refines the edge so it's actually sharp, not just scratched. This is a real sharpening tool, not a quick-fix gimmick.
