The First Double-Sided Dual Grit Flattening Stone

When we set out to create the ultimate flattening stone, our objectives were to create the best flattening stone possible, while still keeping it affordable. We met our goals and we're happy to show you the finished product.

When creating the stone, we first had to define what made a great flattening stone. We came up with 5 important factors.

Guaranteed Flat

When our flattening stone is made, care is taken to ensure that it comes out of the mold flat. That flatness is critical because that is what determines how flat you can make your stone. We take two additional steps when ours are made. First, each stone is hand lapped to ensure flatness. It takes time to do it, but that is the only way to make it flatter. Second, each stone is precisely measured to ensure flatness. If it doesn't pass the test, it is sent back for additional lapping.

Flattening Stone Size Matters

The size of the flattening stone matters for a few reasons. The larger stone is easier to use as your water stone stays on the surface. But total wear is another benefit. Our large (10" x 4") double-sided stone has 80 square inches of total flattening surface. That is almost 3 times the wearable area of other popular flattening stones.

Seeing the Double-Time Flattening Stone next to other popular flattening stones shows the size difference. And, it's double-sided!

Hard Abrasive Materials

We chose green silicon carbide as our abrasive material for our flattening stone because it is extremely hard and the particle shape cuts aggressively. It is harder than aluminum oxide, and also harder than the less expensive black silicon carbide. This makes it ideal for flattening as it cuts quicker and wears slower.

Two Sides for Fast Flattening and Smooth Surfaces

Just like with sharpening an edge, the coarser the grit the faster the cutting action. However, the coarser the grit the coarser the surface it will leave. We experimented with different grits to find the best overall option. We wanted to find a better solution to that compromise. Our solution was to make it double-sided. Something we have not seen on any other flattening stone before.

The coarse side is a very fast cutting 120 grit. Especially when working on coarse water stones, this side provides the necessary cutting action to effectively flatten the stone. However, when flattening finer stones, a coarse grit leaves a finish that many find undesirable. That is why we put a 320 grit surface on the fine side. On water stones 1000 grit and higher, we recommend using the fine side to put a nice surface finish on the stone. The fine side can even be used alone on very fine water stones to put a fresh flat surface on your stone.

In addition, the distinctive grid pattern of the grooves clears waste material quickly and efficiently, aiding the fast cutting action on both sides of the Double-Time Flattening Stone.

Made In the USA

We've supported US manufacturing since we started and that continues to be important to us. When we set out to create our new flattening stone, we knew we could make a great flattening stone in the US. We feel that everyone benefits when quality products are made in the USA. We're not only supporting the economy, but we are producing a product with a quality that everyone can appreciate.
