Why Add an Atoma 140 Lapping Plate?

Even quality whetstones gradually wear unevenly with use.

Over time, the sharpening surface can become dished, making it harder to maintain consistent sharpening angles.

The Atoma 140 is a Japanese diamond lapping plate designed to restore a flat, even surface.

• Quickly flattens worn whetstones

• Diamond abrasive surface for efficient material removal

• Helps maintain consistent sharpening results

• Particularly useful for maintaining stones used on single-bevel knives

• Available with or without a handle

Unlike conventional abrasive flattening stones, the Atoma uses a diamond-coated surface on a rigid plate. It offers excellent flattening performance, although the diamond abrasive will eventually wear with use.

A good lapping plate is one of the most useful accessories you can own if you sharpen regularly.

Leigh's 2 Cents

This is the sharpening setup I'd recommend to someone wanting to do things properly from the start.

One of the biggest mistakes beginners make is trying to sharpen an old, completely blunt knife on a 1000 grit stone.

It can take ages to establish a new edge, especially when you're still learning how to raise a burr.

That's why I recommend the 320 / 1000 / 5000 progression.

The 320 handles the rough work, the 1000 does your main sharpening, and the 5000 refines the edge.

Adding the Atoma means you can maintain the stones properly from day one.

The Shapton cases are another clever feature. They double as sharpening bases and even have drainage holes.

SO much thought went into these stones.

My advice? Practise on your older kitchen knives before sharpening an expensive Japanese knife. Sharpening takes time and practice, regardless of how good your equipment is.

Hi, my name is Leigh, and I’m a chef from Newcastle, Australia.

I’ve been cooking professionally for over 20 years in some of Australia’s top restaurants, and I’m currently cooking at The Signal Box in Newcastle.

Over the years (since 2018), I’ve put together a small collection of high-quality Japanese knives and whetstones that I personally recommend. Basically, if I wouldn’t use it in a professional kitchen, I don’t sell it. Read More
