Barber hones, in general, range between about 3K ( Champion) and 15k+. So any hone you buy is going to have to be checked, by you, to determine its exact grit range. I prefer to use a barber hone dry as the barber would the one from the pocket of his shop coat. A hone may finish differently used dry, or wet, or slurried.

Also, these were made in a really primitive factory, which made the quality of hones somewhat different according to the batch and day of the week, and hangovers. They used buckets and freight scales and a very primitive drum mixer to form each batch, heat was used and that amount, made a difference also.

Do not get me wrong, they did a great job overall and I use a good one often. I have used a Swaty for 40+ years for carving tools and knives also.
