Best High Carbon Knife Sharpener to Buy in 2025
General buying advice — steel, ergonomics, and value per use case.
Direct Answer
Define your use case first, then weigh materials, ergonomics, maintenance, and budget. Favor reputable makers with clear specs and solid warranty coverage.
Step-by-step
- Soak or prep the stone. Soak water stones 5–10 minutes (or use splash‑and‑go stones per instructions). Place on a non‑slip base.
- Set angle and start coarse passes. Hold ~15°–20° and draw the blade along the stone, heel to tip, raising a light burr along the edge.
- Flip and repeat. Work the other side until you feel a consistent burr along the entire edge.
- Refine with finer grit. Move to 3000–6000 grit for bite and polish, using gentle, even strokes.
- Deburr and clean. Strop lightly on newspaper or leather. Rinse, dry thoroughly, and store safely.
