## Product: DMT Dia-Flat Lapping Plate
**Brand:** DMT (Diamond Machining Technology)

The DMT Dia-Flat Diamond Lapping Plate is pretty impressive when it comes to flattening sharpening stones—whether you’re dealing with conventional stones, waterstones, or oilstones. The manufacturer highlights its DMT Hardcoat Technology, which supposedly lasts longer than other diamond coatings. Plus, it's hand-certified to be flat within a super precise tolerance of +/- 0.0005 inches. This means you'll get a consistently flat surface on your sharpening stones.

Our research shows that people really like its aggressive diamond surface, which seems to flatten various types of stones quickly. It even works well on fine grit stones, like [10000 grit waterstones](https://www.shopsavvy.com/redirect?url=https%3A%2F%2Fwww.amazon.com%2Fs%3Fk%3D10000%2Bgrit%2Bwaterstones%26tag%3Dssw.ans.tx-1-20). It's got a solid rating of 4.5 out of 5 stars from 208 reviews, indicating that most folks are pretty happy with it.

On the flip side, you’ve got to be careful with it. Some folks have noticed that its diamond coating can wear down, especially if too much pressure is used. To avoid this, using gentler pressure can help preserve the plate and make it last longer. This tip is worth considering, especially given that the lapping plate isn’t cheap.

So, if precision is your thing and you're careful with your tools, the DMT Dia-Flat Diamond Lapping Plate could be a good investment. It's perfect for keeping your sharpening stones flat and ready to use. Just handle it with care to make the most of it.
