Made in Niigata, Japan, the Suehiro RE-510 is a double-sided combination whetstone featuring #1000 and #6000 grits, ideal for general sharpening and fine honing. The #1000 side handles your basic edge maintenance, while the #6000 side refines your blade to a smooth, polished finish.

Crafted from white aluminum oxide and magnesium-bound, this stone is a splash-and-go type, requiring only a brief soak before first use. The included plastic storage case doubles as a whetstone holder and comes with non-slip rubber feet. A Nagura stone is also included for surface cleaning and slurry generation.
