PDT (PDTools) Premium Diamond – Metallic Bonded

Lapped the stone with 600 sic carbide powder, it has a rough finish out of the box but cleans up quickly. It leaves an interesting finish, it's not a mirror finish despite being 15,000 grit but it does leave a hair whittling edge. The finish might change once I get some more sharpenings on it and break it in, I've only got 2 sharpenings so far but I like the results.

Great course stone for reprofiling edges. My only complaint is that my stone has a smallish bare spot without any abrasives at the surface. Still a great stone, just need to resurface to get a full face of abrasives.

Over time, the need for durable coarser grit stones has become apparent. They allow you to effectively repair damaged blades and quickly set new bevel angles when required. I’ve recently learned a method of minor blade thinning that can be done with my fixed blade system. This method requires extensive use of coarse stones. In short, I am wearing out my ATOMA plates. So I needed another durable option. The 160 grit stone fills that role. I’ve used it once to reset a bevel and it performed quite well. It’s best to break them in with a minor lapping with 80 grit SIC powder. In theory this stone should be quite durable. Time will tell.
