The grits serve three distinct stages of sharpening. Medium (280 grit, green trim) removes metal quickly to reshape or recondition a dull or damaged edge. Fine (600 grit, blue trim) refines that edge for everyday sharpness suitable for most cutting tasks. Extra Fine (1,000 grit, yellow trim) polishes the apex to a smooth, keen finish ideal for precision work. For best results, work from Medium to Fine to Extra Fine, skipping any grit that is not needed based on the blade's current condition.

No lubricant is required. The diamond abrasive surface sharpens effectively dry, which makes these stones practical for field use. You may apply a few drops of water if you prefer a lighter cutting action or want to keep the surface cleaner during use.

A diamond bench stone uses industrial diamond particles bonded to a substrate, making it harder and faster-cutting than traditional aluminum-oxide or natural Arkansas whetstones. Diamond stones work on virtually all steel types including hard modern alloys that resist conventional stones, require no soaking or oil, and maintain a flat surface over time without dishing. Whetstones, by contrast, can develop uneven wear and may require periodic flattening.

Yes, with technique adjustments. Work each individual serration bevel using the corner or narrow edge of the stone rather than the full flat face. Move the stone in short strokes angled to match the bevel of each scallop. The process takes more time than sharpening a plain edge, but the diamond surface handles serrated blades effectively.

Fine (600 grit, LDB6F) is the most versatile starting point for most users. It handles routine maintenance sharpening on knives that have not been neglected, and it serves as the middle step if you later add Medium and Extra Fine to your kit. If your knives are frequently very dull or you work with woodworking tools that need more metal removed, consider starting with the Medium (280 grit, LDB6M) instead.
