Looking at one of these but the blurb is only directed to lapping water stones.

The Dia-Flat™ Lapping Plate is designed to easily flatten all conventional and waterstones faster than any other method. Using the new revolutionary DMT® Diamond Hardcoat Technology™, this lapping plate will outlast any other diamond coating on the market. With a consistent, aggressive diamond surface (120 micron / 120 mesh) and precision ground, hand certified flat to +/- 0.0005”, the Dia-Flat assures rigid execution when flattening stones. It also features a greater surface area for ease of use, sized at 10" x 4" x 0.375". Complete with a durable construction that will provide years of consistent performance and reliable service, professionals rely on the superior quality and versatility of DMT® products for proper tool maintenance. Made in the USA.

I figure a diamond plate is a diamond plate and why shouldn't this one be used to do some heavy work on steel?

Thoughts?

 
Interesting. Seems as though it would work, though you might be overpaying for the purpose. I do have to wonder why they don't mention that as a possible use, though -- maybe there is a reason.

If you do try it out, I hope you will report back on your results.

It's an auction and currently way under retail, so I'm considering giving it a go. I'll report back any findings if I get it.
 
I think 120 micro is way too coarse to sharpen a knife edge. It’s coarser than a extra coarse sharpening stone. It would probably shred the edge pretty badly.

You don't buy a 120 of any kind for that. You buy it when you need to remove serious amounts of metal. Hence TC's reference to "heavy work on steel."
