The CS KOCHSYSTEME TROMSO whetstone is ideal for keeping the sharpness of your blades. The stone has two distinct grits, allowing you to re-sharpen well-kept knives as well as mend dull knives that have been frequently used.

The whetstone is securely held in place on a sturdy ABS plastic tray with slip-resistant feet, which also collects draining water.

The whetstone can be left in the tray after use because of its unique shape, which allows air to circulate around the whetstone, allowing it to dry fast.

This is the ideal whetstone for sharpening blades. To hone down to the optimal cutting edge, each side has a different grit.

How to use: Soak the sharpening stone in the tray for at least 10 minutes before using. Move the blade over the stone in a smooth forward and backward motion with light pressure to a degree of 15-20°. Re-wet the stone as necessary, then clean the blade.
