efficace mais pour dégrossir seulement

### ⭐⭐⭐⭐⭐ Extremely high quality stone plate
*by  on Reviewed in the United Kingdom 18 September 2025*

Excellent quality

### ⭐⭐⭐⭐⭐ Product is listed as "science purchase" but this thing is a true 400grit diamond plate from Atoma
*by  on Reviewed in Canada 1 September 2023*

I'm not sure why this product is listed the way it is with "Science Purchase" in the description. If you consider diamonds science then sure but it is confusing to say the least. This product is in fact a real/authentic Atoma Diamond plate from Japan.Truing stones overtime will eventually lose their flatness but not with a diamond plate. My aluminum block came with a few light surface scuffs/scratches but that's okay. The diamond pad is adhered tightly to the block and will take some prying to remove it when it needs to be replaced in the future.Since this thing is near perfectly flat, this will will flatten/level out any whetstones in no time. It can even be used for knife repair, but I wouldn't recommend that as it'll prematurely wear out the diamonds if you do use it for metal on metal repairs. The 400grit level is perfect as its not as rough as the 140grit but still faster then then 600grit diamond plate.If you're looking for the ultimate way to keep your whetstones flat, then this diamond plate is the way to go. The pricing of $69 is also a steal compared to some other online retailers selling it for $100+ so this is an absolute bargain.
