Pride Abrasive 3000 Grit Very Fine Sharpening Stone, 20cmx7cm surface, 2cm thick.
These are high quality, American-made water stones. They cut very fast and yet are still very long lasting. This 3000-grit is very fine -- fine enough for final edge finishing for many kitchen knives, especially if you don't want an extremely fine/polished edge on your knife.
These are fine to soak before sharpening, but as always air dry between use, and avoid rapid temperature changes to reduce the risk of damage. Only use water to lubricate and clean, no oil or detergents or anything else.
Note: these do not come with any packaging. They will ship to you well-protected, but they do not include any box or stand or anything else.
