Diamond Flattening Stone Lapping Plate Double-sided (120&180) Grit Diamond Sharpening Plate Fixing Stone Flattener SCOTTCHEN

Looks great and priced reasonably! Good for flattening stones and create a new new edge. The plates are removable for washing/cleaning. However, the magnets that hold them are not not glued. Otherwise, it’s easy to maintain. It’s marked “DMD Tools”

Hefty 10" diamond plates stuck to a plastic form with magnets. The first time I took the plates off the form all 6 magnets came out attached to the back of one of the plates. A drop of super glue and replaced the magnets. Easy fix...I put these plates on a stone holder and flattened every stone I had. Lots of water and back and forth with a rotation of the stones every 10 passes. The plates flatten ceramic, silicone carbide, and natural stones (Japanese, Chinese, Arkansas and Vermont slate).Ran the stones over 120, and then 180... All stones were flat using straight edges. No light between straight edge and stone. I used other finer diamond plates ( much more expensive) to finish finer grit stones.These plates worked really well for rough flattening! And for 20 bucks, I'm not afraid to be rough with them. I rejuvenated several old oil stones with noticable dishing to flat and ready to work again. It would have cost me hundreds to replace my old dished stones...Cleanup was simple. You can use a small screwdriver, tip of a knife, or anything to get into the slots to pop off the plates from the form. Wipe any excess water off the plates and form and let dry before reassembling.I'm very happy with these plates. They do show some wear after I flattened 10 stones on both sides, but I honestly abused them pretty hard with those old oil stones. And they still have plenty of grit left and I'll use them for years to come.So if you have beat up old sharpening stones, these plates will bring them back to perfectly flat working condition again with a little elbow grease and water. Well worth 20 bucksUpdate:I really abused these plates... I flattened water stones super easy and the first couple oil stones I flattened had been soaked in degreaser for a couple days before I flattened them.......I started flattening oil stones without degreasing........They worked fine for a minute then clogged up with grease and oil... Black streaks throughout and just caked on there... Absolute mess!I sprayed a little WD and scrubbed them with Scotch Brite and the greasy build up came right off. I dried them and then scrubbed them with a little alcohol and they are clean and ready to work again. I'm pretty impressed with these diamond plates

It’s 2 thin sheets of metal glued to plastic far from flat.

This stone dresser revived all my stones, it works well and is quick to remover material.

Used it to flatten my wet stone but has some imperfections that left big scratches to it
