Sharpener of the Week: Double-Time Flattening Stone

July is “Made in the USA” month at Sharpening Supplies. Our first Sharpener of the Week is the USA-made Double-Time Flattening Stone. Guaranteed flat, and large enough to flatten any water stone with ease, the Double-Time Flattening Stone is extremely hard and cuts aggressively. The double-sided stone has a distinctive grid pattern that aids in fast and efficient flattening, leaving your water stones with a smooth flat finish.

Made and designed in the USA.
