There are three reasons Shapton Sharpening Stones work so well. First, Shapton Glass Stones are made from the most carefully graded ceramic particles on the market.  Second, Shapton stones have a very high density of those particles in each stone.

Third, Shapton Stones have a high degree of uniformity in the distribution of the particles. The even particle distribution results in fast honing at every grit level.

This combination of uniform particle size and the dense, even distribution of those particles makes Shapton Glass Stones one of the fastest sharpening abrasives available.

Another advantage is that you don't have to soak these stones before using them like you would with other water stones.  Just splash on some water and start sharpening

The Shapton 4000 is an extra-fine grit and perfect for creating a razor sharp edge on knives and tools

Shapton Glass Stones are designed for fast sharpening and low maintenance.
