Honing last week sucked. I tried the Gok20k but was getting chippy edges even with jointing and going back to 8k. Next I tried the Ohzuku and the shave wasnt great. So when it all fails I go back to the green Nakayama, raised slurry with 1200 Atoma this time and worked all the way down to water.
This AM the shave was perfect with the 6/8 Dovo. Alum didn't sting a bit. I know that HHT is subjective but after stropping on the fire hose and then the Kanayama this razor is giving silent ones.

Carborundum stones are pretty bad for razors unless they're really fine. Their cut depth is more suitable for high speed steel or something that doesn't fracture.

I've not used one on a razor, but I learned a lesson about them with a Kiyotada chisel. Kiyotadas were sought after in japan for a while (still are to some point), but some of them are not as similar in hardness as you'd expect (I have three). The one of mine that is really hard will literally not tolerate having its bevel set on carborundum stones - diamonds would be out of the question. When you work the bevel on carborundum, it looks fine, and then somewhere around the final stone, it crumbles. I'd estimate the chisel to be somewhere in the 66 range, which a lot of japanese tools claim, but I haven't found to be true when trading time on a versitron (some can be sharpened on arkansas stones, too, which means they definitely aren't close to that).

Anyway, that creates an issue where the steel is too hard to sharpen easily on natural stones, but it won't tolerate anything other than slower synthetics. I got by with an india, but have been careful with the chisel not to damage anything.

totally different thing, though. Japanese carpenters didn't want to be seen sharpening a tool on a job site, so they wanted their tools to be as hard as possible, even though it made sharpening a lot harder. Some english craftsmen did that, too, taking several chisels and plane irons to work (instead of seeing if they could push one all day) and then resharpening them at night while they weren't on the job.

Long useless story, but agree - carborundum and crystolon stones in the coarse variety are a no-no (they are friable, too, when they're new), and when they're fine, I don't know what they are accomplishing on razors, because they cut deep tiny grooves - so they're not fast, but you have to make a lateral move to a slower/shallower cutting stone around the same grit level before you can move up.

Did I mention that I have about 10 carborundum stones? I got them in a machinists lot and found out quickly why so many of the old ones show up without much use, despite the fact that they cost about the same amount as a washita back then. The coarse ones did get used in shops and jobsites, though - but a washita or india stone usually followed them.

Nothing to drool over. Im test a new hone that will eventually be for my tools. But i wanted to see if this could be an affordable option for people on a fixed budget or unsure if they even want to hone. Went from 1k shapton to the test hone bluesun 3k 8k then PHIG.

I honed a Northfield that I just finished cleaning up a bit. It needed a new bevel and the whole works. I went with two layers of tape and used synthetics for part of the progression, then to a coticule. I used a King 1K, Shapton pro 2K, Norton 4K, and a King 6K. After that I went the rest of the way with this coticule. I found it a while back in a lot of dirty stones, it was almost entirely black with crud. When cleaning and lapping I found it had a stamp! But, in order to get it flat and usable the stamp was lost to lapping. Here I used slurry and slowly diluted to water. It gives a terrific finished edge.

How were the results from that 3/8k stone nick?

I shaved of the PHIG after the 3/8 and it was a very good comfortable shave. I only did one pass and there are only a couple areas that a 2nd pass would take care of. I have a thread in hones with what i did. I will try a couple other types of razors but this stone seems to be a good choice for someone on a budget.

NOS Henkotsu kami and the first real test of the new Karasu. I set the bevel on Botan on the Suita, then made sloppy mid-range progress on Suita's own slurry (this stone can actually finish quite nicely, which I did NOT want). I wanted to do my pre-polishing on Mejiro on the Karasu and finish on tomo, to get the feel for the power of this pretty stone. Very happy with the result so far, nice shave in 3 unnecessary passes (you all know the feeling, when you just can't stop scraping your face with that new razor).[emoji12]

That's a beautiful picture, sounds fascinating, wish I knew more about jnats.
