Samura Diamond Combination Stone, #360/#600

The Samura diamond combination stone #360/#600 is a double-sided sharpening stone for the heavy work on your kitchen knives. Use it to remove flaws that have appeared on a blade over time and to bring a worn edge back to the right angle. Its abrasive is diamond, a very hard material.

Grit and sharpening

The grit number tells you how coarse or fine a stone is: the lower the number, the coarser the abrasive and the more material it removes. With #360 on one side and #600 on the other, this stone is designed for rough work on the blade. Start on the coarser #360 side, then turn the stone over and continue on the finer #600 side. Because both grits are on one stone, you can move from the coarser to the finer grit without changing stones.

Once the edge is in shape again, you can continue on a finer whetstone to bring it to the sharpness you need.

Size, weight and warranty

The stone measures 180 × 88 mm and is 38 mm thick, with a net weight of 286 g. It comes with a 2-year warranty.

Best uses

• Removing flaws that have appeared on a blade over time
• Restoring the edge angle of a dull or worn knife
• Rough sharpening, coarser #360 side first, then the finer #600 side
• Preparing an edge before a finer whetstone
• Double-bevel knives, one side at a time until a burr appears
• Single-bevel Japanese knives, bevelled side first

Care and sharpening

Sharpen one side of the knife until a burr appears, then sharpen the other side, and keep the original factory angle of your knife throughout. For single-bevel Japanese knives, sharpen the bevelled side until a uniform burr appears, then pass the flat side lightly over the stone a few times. Repeat the procedure on a fine whetstone if you need a keener edge, and never test sharpness with bare hands; use a piece of paper.
