Atoma Science Purchase Diamond Sharpener (M)

This sharpener works really well and is super easy to use. The size is perfect and it gives a really nice, sharp edge without taking forever. It feels well made and durable, and I really like how smooth and easy it is to use. Definitely a great product for the price and I would recommend it!

efficace mais pour dégrossir seulement

Servus. Um fünf alte Zimmermannsbeitel, ein Zapfeneisen und einen Hobel abzurichten und aufzuarbeiten, habe ich mir den Atoma 400 angeschafft. Im Nassschliff habe ich pro Werkzeug etwa 1 bis 1,5 Stunden gearbeitet. Der Atoma hat seine Abtragsleistung bis heute beibehalten und ist nach wie vor regelmäßig im Einsatz. Daher würde ich behaupten, dass ich den Diamantstein einem echten Härtetest unterzogen habe.

Pietra fantastica. La sua fama eguaglia la fame di acciaio al carbonio

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.
