The Fällkniven Flipstone FS4 is a compact, dual-sided sharpening tool designed for those who demand razor-sharp precision anywhere they go. Resembling the size and shape of a pocket knife, this innovative flip-style sharpener easily fits in your backpack, tackle box, or pocket, making it ideal for outdoor enthusiasts, hunters, and everyday carry users alike.

Featuring two high-performance surfaces, the yellow side uses a diamond abrasive (25 microns) for repairing dull or damaged edges, while the ceramic side (1 micron) delivers a fine, mirror-like polish for ultimate sharpness. Both stones are permanently bonded together, ensuring long-term stability and reliability even after years of use.

The Flipstone’s clever automatic folding design allows you to lock it securely in both open and closed positions, adding a layer of safety and convenience. Like all diamond sharpeners, the FS4 will reach its optimal performance after sharpening around ten knives a natural process that helps the surface “break in” for consistent results.

Durable, lightweight, and built to last, the Fällkniven FS4 is the perfect sharpening companion for anyone who values precision craftsmanship and reliability. Available now at Mjoutdoorsgear UK.
