Possibly, all natural stones are unique as to composition and grit size. Many have used these stones with good results but some are better than others. It is questionable if the grit size is as advertised, few naturals are, but does not mean they cannot produce an very shaveable edge.

While they are well priced, a known synthetic will produce known results.

If you do purchase, get the larger stone, especially if you are new to honing. It will make your life easier. There are many threads on this stone.

Make sure to lap the stone smooth and flat, Loose Silicone carbide or Wet & Dry paper beginning with 220 up to 600 until smooth with no scratches. Then prep the stone face with hard flat steel, like a kitchen knife, 2-300 laps with pressure. The smoother you can get the face the better your results will be.

2-3 drops of Smith honing solution on a flooded stone will yield best results.
