I am thinking to place a special order for plates in 4000, 6000 and 8000 grits for this particular size - 11.5x2.5
DMT plates work very well on alloyed steels with higher wear resistance as well as any steel. They cut very fast.
I have these plates for years now, and am very happy with the performance. I also use them as strop base for pads with magnetic backing. The advantage - you can use different pads with different abrasives, damaged pads are easy to replace (as opposed to strop on a wooden base).
These plates will come with elevated silicone feet, or an optional wooden holder.
I need to order minimum quantities of these plates in each grit. I will also order some 600, and 1000.
If there is enough potential interest, I will contact DMT and get their quote and then convey the prices. I am not sure what they charge these days, haven't purchased from them for a long time.
