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?
