Which stone for scratch removing before finishing stone?

[Better call Leo]

My dear friends!

I have some yanagiba and iron clad gyuto need to re-finish the whole surface (edge).
I am looking for a stone to remove scratch and prepare the edge/surface for final kasumi finish. I have Naniwa Chosera 400-800-3000, and Rika 5k. I am not sure why the Rika 5k create a lot of deep scratch and the finish is much worse than chosera 3k. I remove Rika 5k from my polishing collection. I have some nice Tenjou Suita for final finish. Before the final finish, I wish to find a nice stone to remove the scratch from chosera 3k. Do you have any suggestion? I guess I need a 6k stone or should I find a Mikawa Shiro Nagura for scratch removing?

Aizu, Mikawa Shiro Nagura, a good Aoto, Maruoyama Ao Suita (Ive got two, one is a pre-finisher one is basically a Shiro Suita ), softer Uchigumori. This list is not ordered, it just depends on individual examples and what you like

many finishers can pick up directly after chosera 3k if you're REALLY thorough.

I like Aizu a lot personally

For complete scratch removal, SS5k? I usually end up pretty clean after the 3k, and the 5k does the rest unless I start the natural progression. Keep in mind the 5k still does leave scratches.. I once in a while go up to 12k to completely delete core steel scratches, but I find that unnecessary if you’re going to a natural stone afterwards, as I don’t have a jnat fine enough to produce a hard mirror.

The best I’ve found is a super soft Hideriyama. Probably a level 2.5-3, lands squarely between binsui and low finishers. JNS has some small aiiwatani and super cool takashima kan for “decent” prices, I imagine those could be ideal.

Honestly, I sometimes don’t even go to the NP3k. I don’t love how it polishes, and if I’m after kasumi a natural progression is easier to control and tinker with after NP1k. I have a couple stones that work amazing at that scratch-deleting range, but as you know with jnats, it’s hard to get the same results even from the same pedigree.

Shapton 5k, the hard stones leave deep scratches, soft stones don’t.

You can replace shapton 5k with Shiro Nagura

I like the arashiyama 6k a lot for this exact task. I use it usually after shapton 2k to remove the scratches from that, so it should also work well for 3k scratches

I love my mikawa nagura, it leaves an amazing edge too. Get one if you can. JNS has them in stock

No personal experience with the Rika 5k, but from BDL's description in Cheftalk I remember him saying that it starts at some 3k, and only gets finer when the particles have broken down.
As for the Chosera 3k,the particle size corresponds more to a JIS 4k.
