Well the 800/1k and both strops got here. So far I'm really having trouble getting a sharp edge. Probably a combination of the stones being so new and the burr not getting stropped off. Not even close to a mirror either lol.
If you are hitting the edge properly, you should be seeing an extremely sharp edge with just the 600 grit stones.
Use some sharpy and a loupe to see what's going on there. Finding the sweet spot is also important. That's how far forward or backward to mount the knife to hit the edge as even as possible heel to tip.
As to the mirror finish, it won't happen while the diamond paste is still smearing around. Once the paste impregnates and no longer leaves a mess on the blade, the polishing will happen. It still takes time to buff out the 1000 grit diamond scratches so try very fine sand paper if you want to go faster. If you are stropping a lot, use very light pressure and maybe back off a degree or two. It's just like hand stropping, too much angle or pressure combined will actually dull your edge.
Practice makes perfect. Once you get a feel for it, you will be very happy with the sticky sharp hair splitting edges you can achieve.
