Unlike other whetstones these are laminated to a glass backing, preventing cupping (regular stones can warp and cup as water enters between particles). With a uniform particle size, they cut fast and are hard wearing, and don’t need pre-soaking before use – just a splash of water is all that’s needed.
They are considered the very best stones available. This medium grit #1500 is perfect for regular use and comes in a handy storage case (with air vents). The case also doubles up as a rest for sharpening.
The perfect partner to any Japanese knife.
