Surgical Black Arkansas Sharpening Stone - 6 x 2 inch

Eternal Tools

The Surgical Black 100% Natural Arkansas Sharpening Stone is one of the finest grades of abrasives available today.

An extremely hard, dense material, this natural stone is known for developing an extremely smooth edge and developing a deep, rich sheen to your blade or tool.

The stone is naturally very durable and will not require lapping or flattening.

This stone is commonly used for industrial applications like sharpening dental instruments and gold testing where an extremely fine polish is required. All bench stones come with a custom wooden box for storage.

  • 6 inch x 2 inch x 1/2 inch (150 x 50 x 12.5mm)

Grit size in comparison to synthetic stone: 4000-6000 grit

How to Use our Natural Arkansas Sharpening Stone:

1. Apply a small amount of honing oil on the stone. 

2. Position your blade or tool across the stone's flat surface

20-22 degree for a hunting or kitchen knife for instance

10-15 degree for a straight razor

Helpful note: Always try to maintain a consistent angle

3. Draw and push the blade as though you are slicing a thin slice off a stone

4. Use the same number of stroke on both sides (exceptions: Razors, single bevel and Japanese knives)

3-10 strokes per side


These stones are 100% natural Arkansas stone made from Novaculite.

 Thanks for taking the time to review these Andy, that's great to hear. 

what grit are these stones?

Joseph Scuderi

As the Arkansas stones are made from natural stone we can't give an accurate grit size. However, in tests it has been found that the following grit sizes are how they compare to synthetic stone:

Hard Arkansas - 800-1000 grit

Surgical Black Arkansas - 4000-6000 grit
