Atoma 140 Grit Diamond Lapping Plate - No Handle

The Atoma 140 Grit Diamond Lapping Plate is the professional standard for fast and precise whetstone flattening. Manufactured in Japan by Tsuboman, Atoma plates are trusted by sharpeners around the world for their durability, consistency and perfectly flat performance.

If you take sharpening seriously, flattening your stones is essential. The Atoma 140 removes material quickly and efficiently, restoring a true flat surface even on the hardest whetstones.

Why choose 140 grit

The 140 grit plate is ideal for

• Rapid whetstone flattening
• Removing glazing or loaded stone surfaces
• Correcting uneven wear
• Light chip repair and aggressive steel removal

It is coarse, efficient and purpose built for maintenance rather than polishing.

Built for precision and longevity

Atoma plates use mono crystalline diamonds bonded to a precision machined aluminium base. Unlike traditional flattening stones, the Atoma remains consistently flat over time, ensuring your whetstones stay true.

• Ultra flat aluminium base
• Replaceable diamond abrasive sheet
• Lightweight yet rigid construction
• Suitable for use dry or with water

When the abrasive surface eventually wears, you simply replace the diamond sheet rather than purchasing an entirely new plate.

Why this matters

A flat stone produces a consistent edge.
A consistent edge improves sharpening results.
Better sharpening results mean better performance from your knives.

For anyone maintaining premium Japanese kitchen knives, the Atoma 140 is an essential tool.
