Question 1

Why does my diamond stone feel aggressive at first but smoother over time? Is it wearing out too fast?

Accepted Answer

It’s normal! The rough surface sharpens aggressively at first. With use, it smooths, exposing more diamonds for consistent performance. The break-in varies but usually takes several uses. Your stone isn’t wearing out—it’s adjusting for long-term use!

Question 2

Is water or oil required during the sharpening process?

Accepted Answer

Avoid using water during sharpening, as it may cause the iron filings on the stone's surface to rust. Testing shows minimal difference in sharpening performance between using oil and dry sharpening, so oil is not necessary.

Question 3

After using the stone, dark areas appear on its surface. Does this mean the diamonds have worn off?

Accepted Answer

No, the dark areas are dried dirt from sharpening, not a sign of the diamonds wearing off. These marks don’t affect performance and can be left as is. For minor marks, use an eraser. For tough stains, clean with Bar Keepers Friend and air dry fully.

Question 4

Should I use high pressure when sharpening with this diamond stone?

Accepted Answer

Avoid applying excessive pressure when sharpening, as it can accelerate wear on the diamond and shorten its lifespan. Instead, use light pressure to maximize the sharpening performance of the diamond particles.

Question 5

How long does it last?

Accepted Answer

The lifespan depends on usage, the hardness of the materials being sharpened, and maintenance. With proper care, it can last many years, even for those sharpening 3 to 4 times a week. Regular cleaning and light pressure extend its durability.

Question 6

How to clean the diamond stone?

Accepted Answer

To clean the stone, gently wipe the surface with a dry paper towel. If particles are clogged, use a rubber eraser or nylon brush to remove them. This will restore the stone to its original condition.

Question 7

The stone I received has some small pits on the shorter sides. Is this normal?

Accepted Answer

Yes, this is normal. The pits are caused by clamps used during the electroplating process and are not a sign of defects or prior use.

Question 8

Which version should I choose: 162N 8" x 3" or 156N 6" x 2.5"?

Accepted Answer

If budget allows, choose the 8" x 3" version for its larger surface, which is more efficient and easier to use for knives 8 inches or longer and tools. The 6" x 2.5" version is compact and sufficient for knives 6 inches or shorter.

Question 9

What is the cause of the rust and how can I deal with it?

Accepted Answer

The base of this product is stainless steel and will not rust. Any rust is caused by iron filings left on the stone's surface that oxidize if not cleaned. Use Bar Keepers Friend powder to clean it and ensure the stone is fully air-dried.

Question 10

Is it normal to see scratches on the surface after sharpening with this diamond stone?

Accepted Answer

Yes, it's completely normal. The scratches are just typical signs of use and do not affect the performance of the diamond stone. The diamond layer remains intact, so its sharpening ability stays as effective as ever.
