I have offered DMT in the past and will resume offering 8x3, 10x3, and 11.5x2.5 plates in 600, 1200 and 8000 (only 8x3" in 8K grit) grits. A felt strop with magnetic backing will be available for each size.
I personally think sharpening on diamond plates is the way to go. It's efficient (fast), user friendly (no flattening needed), gives a bite to the edge (in any grit), and plates can be used as bases for strops. I will offer DMT plates with custom wooden bases, or without (but with oversize non-skid feet that will elevate the plate to the level where it needs to be for comfortable sharpening).
Diamond rods could be used for a quick touch-ups or to sharpen scallops on a bread knife (at least on my knives).
I have used these diamond plates on steels I offer, and combined with strops, these do amazing things to the edge. I have convinced a couple of guys to give it a try and one reported that between stropping and 8K touch-up he was able to extend time between sharpening to 3 months in a pro kitchen. And that was a 52100 knife with my earlier heat treatment.
This is more about bringing a product that I consider to be very good, rather than product I can make money on. I think it's a perfect fit for a pro and home environment.
Will be offered soon:
11.5x2.5" (my favorite size)
