ATOMA Diamond

Atoma diamond sharpening stones are high-quality monocrystalline diamond stones manufactured in Japan, known for achieving excellent test results. These full-sized sharpening stones measure 75x210 mm, making them almost the same size as standard whetstones and significantly more efficient than narrower diamond plates.

The diamonds are attached to the surface of a metal plate using a regular placement technique, which is then glued to an approximately 10 mm thick piece of aluminum. Although technically not stones, their long lifespan makes them ideal for home kitchens and industrial sharpening needs. In-home use, Atoma diamond sharpening stones last almost indefinitely and have also been successfully used to sharpen industrial tools.

Atoma diamond sharpeners are particularly suitable for flattening water stones. The systematic arrangement of the diamonds effectively prevents the sharpening stone from sticking to the water stone being sharpened. All Atoma grits are suitable for flattening and sharpening stones, but the best results are achieved with grits 140 and 400.

New Atoma diamond sharpening stones may feel coarser than the stated grit, but once the sharpest edge is worn down, they retain their grit for a very long time.

Why Choose Atoma Diamond Sharpening Stones:

Durable and long-lasting
No need for flattening
Even diamond placement allows for sharpening smaller tools
Better sharpening results than traditional diamond stones
It is easier to maintain the correct sharpening angle across the entire blade
Ideal for flattening Japanese whetstones

Atoma 400 corresponds in grit to the Naniwa Professional 400 whetstone, delivering very similar sharpening results.

Grits:

140 = Very Coarse
400 = Coarse
600 = Coarse
1200 = Fine

Usage Tip:

The manufacturer recommends always using the diamond sharpening stone with water. This makes sharpening smoother and extends the stone's lifespan. Also, avoid using excessive force.
