## Description

Grit: Medium Raw #400; Type: Diamond; Size: 20.3 x 7 x 0.81.3 cm high

Review: This I think is a great sharpening plate, I used to remove the initial covering on a chisels flat side and to get the plate primed for use - I really like it, expensive but worth it
Review: 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.

If you are serious about knife sharpening this is a must. Flattens stones well and quickly (if you do it regularly) and is a joy to set new bevels, very quick and efficient. Not as smooth as a regular whetstone but this is only really used to prep, repair and maintain the stone or just set up the bevel at the angle you wish to sharpen by removing old material quickly. Itll even grind the print off your fingers if u rub em enough, ask me how i know. Its kind of expensive but it lasts long enough to be negligible in the long term. Would buy again (i did).
