I'm running through an entire progression on a set of metallic bonded diamond stones from practical sharpening that I recently received in a pass around group right now. 150/300/500/1000/2200/5000.
These stones are pretty impressive. I started with the 150 for the initial reprofilie ot a factory edge. I wasn't aiming to change the edge angle necessarily, the factory grind was just wonky and wavy. This was probably the fastest/easiest reprofile ive done. Great stone for this purpose. The 300 I've used previously, and is a good candidate for your first stone on your routine sharpenings. It does a good job of resetting the bevels without being overly coarse.
The 500 was a real surprise. It was way smoother than I expected. Very pleasant feedback. The 300 felt rougher while sharpening than a coarse dmt, but the 500 feels much smoother than a fine dmt. I really like this stone.
The 1k, and 2200 were no problem, good performance.
The 5k again was fine. The polish left from the 5k wasn't as high as I had hoped, but that ultimately isn't very important to me.
I decided to go ahead and finish on a ceramic stone per usual, loaded with diamond spray. I did some burr reduction, then actually went back to the 5k and did some alternating honing passes. I checked the edge on a hair prior to stropping, and it is the sharpest edge straight off the stones I've ever achieved, and maybe one of my sharpest edges ever. Hairs just jumping off the edge. Very cool.
Initial thoughts after first full sharpening: If you like sharpening with diamond plates, but dislike how they wear, and lose their aggression, and having to guess at how much sharpening life they have left, these are an excellent option. Being able to etch them and bring back the initial aggression is an amazing quality. You can also customize the aggression to your taste depending on etch time. Generally speaking I think they leave a finer, more consistent scratch pattern, with shallower scratches. If you like sharpening on Japanese waterstones, and are looking for a diamond stone that feel like waterstones, these probably aren't for you.
