Description

The Atoma Advanced Diamond Sharpening Plate #400 Grit is a versatile tool designed to flatten dished whetstones and replace traditional whetstones up to 500 grit. It offers the perfect balance between coarse and fine grit, making it suitable for a wide range of sharpening tasks.

Compared to traditional whetstones, the main advantage of using an Atoma plate is its ability to remain flat over time, providing consistent performance and longevity. The Atoma #400 is a staple grit for general whetstone flattening, covering a range from low grits to high polishing grits.

To use the plate, mount your whetstone in a stone holder and rub the Atoma plate on top of the whetstone in various directions until the stone is effectively lapped.

Atoma Diamond Sharpening Plates are products of Tsuboman, a highly regarded Japanese manufacturer known for their refined diamond products. These plates are made of mono-crystalline diamonds with a cutting abrasive surface mounted on a 10mm thick stainless steel base. The base is machined to be extremely flat, ensuring the diamond plate remains flat throughout its use.

The quality and durability of Atoma plates are among the highest available on the market. They feature precision-made surfaces with high uniformity, maintaining their flatness even after prolonged sharpening sessions. The diamond plate can be replaced after a few years without purchasing another baseplate, as they are adhered using strong double-sided tape.

Atoma Diamond plates can be used dry or with water, depending on personal preference.

Dog likes some
Size: Extra Small, Color: Blue
Puppy will chew on this but not favorite. Over time it gets sharp pieces and dog could ingest. Not sure how safe for a small dog. Affordable but not long lasting.
