Buying Guide
What should you consider when choosing an 800 grit sharpening stone?
- Sharpening goal: If you need quick edge refresh, choose medium-coarse 800 grit stones like the King Pro or King Medium Grain. For finishing polish after sharpening, pair with a finer stone or a higher-grit side in a dual-set.
- Stone type: Natural stones are often praised for feel, but synthetic ceramic and aluminum oxide options provide consistency and faster material removal. Ceramic stones like the SS-800 offer durability and flatness.
- Size and handling: Smaller stones are portable and convenient for tight spaces but may require steadier hand control. Larger stones offer stability for longer blades but take up more space.
- Base and carriage: A non-slip base reduces skew and improves safety. Some sets include angle guides to help beginners maintain the correct sharpening geometry.
- Maintenance: Water stones require soaking before use and periodic flattening. Oil-based stones demand oil lubrication, which some users dislike for kitchen knives.
- Blades and usage: For kitchen knives, ensure the grit and hardness suit typical steel types. For chisels or tools, consider coarser or dual-grit sets to cover broad ranges of edge restoration.
Frequently Asked Questions
