Run the focus all the way opposite from what you now have and you should see the higher power, also get closer to the bevel, touching or almost touching.

Experiment with blade angles, I find that rotating the scales all the way opposite the edge at 90 degrees works best, then hang the scales off the edge of a ¼ in piece of craft foam. The blade is on the foam, the scales off the foam. This puts the bevel parallel to the scope lens.

You are rolling the edge, in the 1.5 and 2k stone pics, Forget about the slurry, (you don’t need it with an aggressive stone) and watch your pressure. What strokes did you use? Looks like too many laps on one side or too much pressure. Stropping between stones or light finishing laps will remove the rolled edge.

Edges do not get straight until about 8k, so don’t worry about straightness till then. Set the bevel at 1k, make sure the bevel is fully set, look straight down at the edge, looking from the side will tell you if you are honing to the edge, but not if they are meeting fully. You can look at the edge with the 60 power. If you see shiny reflections the edges are not meeting.

You also don’t need a 1, 1.5, 2k progression, pick one or just set at 1k and do a few light 2k to clean up the 1k stria and spend less time on the 4 or 5k. It won’t hurt but it is not needed.

The grit on your stones are probably the same at other Shapton stones, it is the binder that is different and where they cut cost, hence the price difference, they are probably softer than the Pro or Glass series.

When you take your photos you need to wipe the bevel better, the horizontal lines on the bevel are, dried swarf, wipe with a clean, dry paper towel to remove all the swarf prior to photographing.

Your 15k photo looks like the bevel is not set, looking straight down will confirm. It also looks like you are not honing to the edge in some of the Pics. Use some sharpie ink to ensure you are honing to the edge.

The 15k photo looks like there is still some 1k stria on the bevel, this will make a chippy edge at 15k. Spend more time with each stone and remove all the previous stria.

If you micro-chip the edge you do not have to go back to the 8k, just joint the edge on the 15k and re-set it, should only take 6-10 laps and watch your pressure.

Everything you are experiencing is normal to a new honer, soft stones make the learning process harder. You just have to learn to read the bevels and use less pressure.

There is a good series of post by PCM in the honing forum with excellent photos of the process from start to finish. Starting with, Second try at Honing.

Compare his edges and bevels to yours.

Most of my thoughts Echo Euclid's. Guess I must be coming around because I'm finally starting to agree with him

The other thing I wanted to point out is that a chippy edge is common on 1K hones. Yes, the general consensus is that Shaptons are faster/more aggressive than most. A lot of folks use the 1.5 or 2K as a bevel setter and save the 1K for repairs or use a very light touch with it. That must be what Onimaru was talking about when he mentioned cringing at the mention of pressure on a razor - the chipping and stria will be deeper and much more pronounced on a Shapton 1K if you aren't careful, and that will mean more work at later stages in honing trying to get rid of said chipping. You can mitigate that by lightening up on pressure, using almost none by the time you're done with the 1K, jumping up to the 2K and continuing on with minimal pressure. After 1K, the bevel should be set and you're just cleaning up stria and polishing. No need to start with heavy/medium pressure each time you transition to a new hone.

I also notice in your 1K and 8K pictures the bevel looks set, as much as you can tell from a sideways picture at any rate. But in all the rest I see a hint of white at the edge. That indicates there's a flat surface there for light to refract off of, and if your bevel was meeting there wouldn't be anything there to catch and reflect light like that. So whatever it is you're doing between stones is messing up your edge, or you're taking pictures of different areas and it isn't set in some places.

I usually just refresh them after every 2-3 razors with a few circles on the well worn dmt 325 and they stay flat enough for my standards. I believe it was mainaman that originally peaked my interest in these stones. If I recall correctly they are the exact same as the shapton pro series, just only sold for the japanese market.

The 5k still has a slight, but much reduced burr.

The 8k and 12/15k are failing to reach the edge. You said that you spend the bulk of your time on the 5k and 8k. That may be part of the problem. You really don't need to spend much time on the 8k. Also, you said that you are doing maybe 25 strokes on the 12/15. I have not used your particular hone set, but if they are anything at all like the Shapton Pros, you are doing WAY too many strokes on the 8k and 12/15k. Try doing only 10-15 strokes on the 8k and no more than 10 on the 12/15k.

Also, are you using tape? If so, you definitely need fresh tape on each of those last two hones? Worn tape lowers the spine and lifts the edge away from the hone.

Alright so there is quite a bit to cover here pretty much the common theme here in terms of my honing is that I'm applying too much pressure on my edges causing them to roll/burr. i only use the 1k when there is excessive damage that I have to clean up so I'm usually going 1.5k to 2k. I think I need to find some threads with some pictures of rolled/burr edges so I can take proper measures to fix it early rather than moving up to the 5k 8k and making it smaller. I do use tape and I actually only change the tape after the 2k so changing the tape though the higher grits makes sense on how that can effect my angle in the higher grits.

The scope is use isn't the veho or a usb microscope at all, I bought it on amazon and it's an old fashioned scope. so the light that's used for it is the one actually for the scope. But I'll definitely play around with the angle like was suggested
