Samura Combination Whetstone, #1000/#3000, 185 × 65 × 32 mm

The grit number tells you how fine a stone is: the higher the number, the finer the abrasive and the smoother the edge it leaves. The #1000 side sharpens the blade and removes small flaws and signs of wear from the cutting edge. The #3000 side then refines the blade and the edge for the finish. This versatile pairing covers both steps, rough sharpening and finishing, and you can use it at home, even on good-quality knives made of dense steel.

The stone measures 185 × 65 mm and is 32 mm thick, with a net weight of 616 g. It comes with a 2-year warranty.

• Rough sharpening of dull kitchen knives on the #1000 side
• Removing small flaws and signs of wear from the edge
• Finishing the edge on the #3000 side
• Double-bevel knives, one side at a time until a burr appears
• Single-bevel Japanese knives, bevelled side first

Before use, submerge the whetstone completely in water for 10–15 minutes and keep it wet while you sharpen. Sharpen one side of the knife until a burr appears, then sharpen the other side, and keep the original factory bevel angle of 15–17°. For single-bevel Japanese knives, sharpen the bevelled side until a uniform burr appears, then pass the concave side lightly over the stone. Repeat on the finer #3000 side if needed.

Samura sharpening tools help you keep kitchen knives sharp without much effort. Whetstones in different grain sizes help you restore the right edge angle, and the range also includes other combination whetstones, a honing rod and a sharpening angle holder.
