The Norton Water Stone NT450 is a double-sided sharpening stone featuring 1000 grit on one side and 4000 grit on the other.

Measuring 8″ × 3″ × 1″, the stone is made from ceramic and is designed to use water as a lubricant, without the need for oils or pastes.

The stone weighs over 1.5 lb and comes in a blue storage box for protection. A complete set of instructions for sharpening and polishing is also included.

SPECIFICATIONS

The fastest cutting oil stones are made of Silicon Carbide.

The silicon carbide stones made by Norton are called Crystolon stones.

These stones are also labelled fine, medium, and coarse, they are usually Grey in colour.

While these stones will not produce an edge as fine as the India stone, the fast cutting makes them ideal for initial coarse sharpening.

Because they sharpen quickly, it a common practice to use the Coarse Crystolon Stone and then progress to an India Stone.

The oil filled stone is self-lubricating, however it is still recommended that oil is used when sharpening.

The non-oil filled stone requires a lot more lubrication and various other lubrications can be used for sharpening such as water for example.

Silicon Carbide is preferred for faster stock removal if the knife is chipped or highly blunt whereas Aluminium Oxide is preferred to finish the edge being a slower cutting stone.
