Samura Combination Whetstone, #3000/#8000

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. Start on the #3000 side to sharpen the edge finely. Then turn the stone over and finish on the #8000 side to polish it.

The stone measures 185 × 65 mm and is 32 mm thick, with a net weight of 534 g. Its size suits both long kitchen knives and small folding knives. The whetstone comes with a 2-year warranty.

• Fine sharpening of kitchen knives on the #3000 side
• Final polishing of the edge on the #8000 side
• Long kitchen knives as well as small folding knives
• 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, keeping 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 #8000 side if needed.

Samura sharpening tools are made to sharpen kitchen knives without much effort. Alongside whetstones in various grain sizes and other combination whetstones, the range includes a honing rod, an electric sharpener and a sharpening angle holder.
