140 Grit Diamond Stone Flattening Plate. This one measures 8" x 2.75". These plates are not dead flat like the DMTs or Atomas which are 2 or 3 times the price but they are perfectly fine for flattening your stones or if you want to champfer the edges or for quick metal removal. If you're concerned about this pay the extra money and buy the DMT XXC or the Atoma 140 grit diamond plate. We offer them both on our site.

Rapidly flattened three waterstones soon after arrival, and doesn't appear to have lost any diamonds while doing so. Haven't measured against an engineers ruler, but certainly flat enough to do the job.

5  ďDead flatĒ for the average person, February 24, 2019
Posted By: Dave McShea - verified customer

Other than my Lanskey diamond sharpening set that I use for my pocket knife collection, this is my first experience with a diamond plate for kitchen knives. The 3X8 diamond plate did an excellent job of flattening my whetstones and left a nice finish. From the reviews I read, I thought I was taking a chance in terms of flatness. I do not own any machinist measuring equipment, but can confidently say that this diamond plate is for all intents and purposes dead flat. I own a large marble pastry board and a locally sourced piece of marble that I use as a sink bridge, and when I lay the diamond plate on either one while wet, it creates suction. Therefore, I can only assume for the average user not performing microsurgery, that this product clearly outperforms the competition in terms of value. My next purchase will be the 80 grit, followed by another 140 grit to be used exclusively for oil stone flattening. Another home run for Mark and Chef Knives To Go!

There's a slight amount of bow on the surface, but the price difference between the DMT plate makes up for it.

Nicely constructed plate. Diamonds appear well and evenly distributed. Good aggressive surface.
Have not yet used it for flattening water stones such as the Shapton Glass bench stones, but it looks to be up to the job.

Posted By: Ben Hulsey

At it's price point it can't be beat. It'd be nice if it were a touch larger but again, it's $30, so I can't be anything but thrilled. Stone's not grabby like my old DMT and hasn't been losing it's grit like the DMT.

4  cost effective metal removal, April 23, 2018
Posted By: Peter Cowick - verified customer

Not flat enough for finish stone flattening, but cost effective for quick metal and/or rust removal, to change a bevel angle or curve and/or flatten a cutting edge. Haven't used the plates long enough to determine how long they will last. They have a place in my sharpening equipment.

As a guy that likes to cook at home, no need to spend top dollar on a flattening plate unless your frequently use your stones. Solid and necessary buy in maintaining your stones.

5  Just buy it, January 23, 2018
Posted By: Haydn Roberts - verified customer

I have used this diamond plate for a couple of tip repairs, grinding down the bolster on two Wusthof chef knives and removing and re-profiling the edge of a terribly abused Mac MTH80. It performed all these tasks admirably but be warned, it cuts quickly. I have also used it to dress my Shapton glass stones, which it did very well. Regarding flatness, it certainly seems flat to me. I have neither the equipment or the desire to measure it's flatness but really, how flat does it need to be? Bargain. Just buy it.

So far as I've used it, it works beautifully. Dries up quickly, and doesn't take up much space. The stones are silky smooth, and what more could I ask for?Hopefully it'll last a while, and prove to be an excellent value for money.

5  Useful for Fast Metal Removal, August 17, 2017
Posted By: Dan Streng - verified customer
1 people found this review helpful

This removes metal fast when it is necessary to create a new bevel or when knives are very dull or damaged. It is a good value for a tool of this type and saves a significant amount of time over using even a coarse stone. The initial bevel is the most important stage IMAO (in my arrogant opinion). Everything else is refinement.

4  Nice diamond plate, May 21, 2017
Posted By: Ari Baranson - verified customer
1 people found this review helpful

This is a decent diamond plate. It is my first one so I have nothing to compare it to. However, it flattens all of my stones well, and is easy to use. It is a little hard to hold so I recommend laying it flat and rubbing the stones on it rather than rubbing it on the stones. I have found that it leaves a smooth finish that is not to coarse. My only complaint is that the back has an odd chip/extra bit of metal. However, this does not hinder the process but would prevent me from laying it completely flat on the counter, but I use a rubber gridded mat anyway. Works well and is great for the money. Certainly recommend for anyone on a tight budget

5  140 Grit Flattening Plate, November 6, 2016
Posted By: Frank K - verified customer

First used to repair a long neglected soft Arkansas stone. Worked great and the stone is almost good as new. Then used the plate to repair the tip of a hunting knife, which took only moments. Finally, I got around to flattening a new combo water stone. Surprisingly, the stone was almost perfect from the get-go. The plate is a very nice tool that is very reasonably priced.

4  More than pleased!, January 5, 2016
Posted By: Brian M (GopherBroke) - verified customer

I ordered this on New Years Eve day, and it's already here (Jan 4)!I ordered from somewhere else on the same day... and they have not even processed my order yet!So kudos to Mark and the crew, again!On to the topic!I was surprised when the plate arrived that the entire plate (all 6 sides) are nickle/chrome plated, so no need to worry about rust :)The finish on the plate looks great; no bare spots etc.I'm the curious type and have to know everything! I've been that way since birth and every hobby/interest becomes an obsession. Each obsession lasts until a new topic comes along that interests me and then I veer off...Flatness:I measured the flatness of the plate with an Interapid dial indicator that is accurate to 0.0001" What I found was that across the width of the plate (top, center, bottom) the plate has a twist that varied .0003"Lengthwise the plate was within .0005".The work surface being measured on was certified to be within 0.00005" over the entire 18X18 surface.This is flat enough for me!I've never used an Atoma, so I can't speak first hand... but I'm happy with my $30 diamond plate, and the $50 savings. Only giving it 4 stars for now because I can't comment at all on longevity or life of the diamond.

3  Good for coarse shaping of a blade, not so much for flattening a stone, February 11, 2015
Posted By: Dan N. - verified customer

I made the terrible newbie mistake of attempting to use a beautiful Blue Steel Japanese chef's knife to separate lamb chops (cut through a bone) and was rewarded with a 1mm deep nick in the blade edge. I used this basic diamond plate to re-shape the knife edge and prepare it for the remaining work, done on a succession of Shapton Pro stones (1000, 2000, 5000, 8000). The knife turned out great and I've been using it ever since. So as a very coarse shaping tool, this plate does the job.

Posted By: C Flanagan - verified customer

Excellent value. I have two, one for knife repair and one for flattening/ slurry.It's performed fantastically for tip repair. Cuts very quickly, with a decently even scratch pattern. By the same key, it brings up swarf instantly on a moderately hard stone.Each plate did have one tiny flaw, a raised bit at some point along the edge. It's not a dealbreaker (I filed it right off) but it will need to be addressed before flattening finer stones. For the price, I think it's perfectly acceptable.
