FÄLLKNIVEN FS4 FLIPSTONE

The Flipstone grindstone is an automatically folding grindstone that can be used on two sides. Its dimensions can be compared to those of a pocket knife. The FS4 is slightly larger than the FS3. So you can always carry this sharpening stone with you. The yellow side is a diamond grindstone with a grain size of 25 microns. The cut can be restored with this side while the maximum sharpness is achieved with the ceramic side of the whetstone. Both whetstones are glued together and will not come loose.

Although the grindstones are obviously harmless, they can be locked in the folded or unfolded position.

As is often the case with diamond grindstones, the surface has to be 'carved in'. Only after sharpening a knife or ten will it have assumed its final sharpening properties.
