15 to 20 degrees for kitchen knives
Most kitchen knives perform best at 15 to 20 degrees per side (30 to 40 degrees inclusive angle). This balances sharpness with edge durability for food preparation tasks.
Lower angles (10 to 12 degrees per side) create extremely sharp but fragile edges suited to Japanese-style knives and razors. Higher angles (25 to 30 degrees) are used for heavier tools like cleavers, axes, and machetes that need impact resistance.
Consistent angle matters more than speed
Place the stone on a damp towel to prevent slipping. Hold the blade at your chosen angle and draw it across the stone in smooth, even strokes. Maintain the same angle throughout. Consistency matters more than pressure or speed.
Work one side until you can feel a slight burr (a thin ridge of metal) along the opposite edge. Then switch sides and work until the burr transfers back. Finally, make a few light alternating strokes to remove the burr.
Hone regularly, sharpen rarely
A honing steel (the rod that comes with knife sets) realigns the edge between sharpenings. Use it before each cooking session. It does not remove metal; it straightens the microscopic edge that folds over during use.
Actual sharpening on a stone removes metal and should be done only when honing no longer restores the edge, typically a few times per year for home kitchen use.
- Kitchen knives: 15-20 degrees per side
- Axes and cleavers: 25-30 degrees per side
- Sharpen until you feel a burr, then switch sides
- Hone with a steel before each use; sharpen on a stone a few times per year
- Consistency of angle matters more than pressure or speed
