Chroma Knife Sharpener

Yes, an 800-grit stone is an excellent starting point. It is considered a medium grit, meaning it is aggressive enough to restore a dull edge but gentle enough that you are unlikely to remove too much metal if your technique is still developing.

Yes, this whetstone requires soaking in water before use. You should submerge it until bubbles stop rising, which indicates the stone is fully saturated and ready to provide the necessary lubrication for sharpening.

No, this flat whetstone is designed for straight-edged blades. Using it on serrated knives will likely damage the serrations and ruin the stone's surface.

After use, rinse the stone with water to remove any metal filings and wipe it clean. Allow it to air dry completely in a well-ventilated area before storing it, as putting a damp stone away can lead to mold or degradation.

The rubber base is designed to be a stable, non-slip foundation for the stone during use, but it is typically removable. This allows you to clean the stone thoroughly or replace the base if it wears out over time.
