Detailed information

Product detailed description

Small oil sharpening stones SK11 are designed for sharpening tools or for removing burrs on the edge or on a cut metal object. They come in various shapes and grit sizes. To work with them, a special sharpening oil is required, which ensures the proper removal of the ground particles, a better surface finish, and less wear of the sharpening stones. This conical sharpening stone is designed for round chisels, carving knives, and other tools with a round edge profile.

To keep the oil stones in good condition, they need to be cleaned from time to time. For this purpose, it is best to use mineral oil or turpentine. Flattening the worn oil stones is done in the same way as with water stones - using a flattening stone or water sandpaper. However, you should use one of the above-mentioned oils for flattening.

Which grit to choose?

For sharpening really dull or uneven blades, use stones with a low JIS number (Japanese classification for grit size). The lower the number, the coarser the stone. Stones with a high JIS number are intended for final and fine sharpening or smoothing.


  • #120 to #600 JIS: for dull and uneven blades
  • #700 to #2000 JIS: for normal sharpening
  • #3000 to #5000 JIS: for fine sharpening of quality blades
  • #6000+ JIS: extremely fine stones for smoothing or removing scratches
