Saw this @ SRD. As I'm going to buy a Chosera 1k anyway, I'm wondering how this compares to the original that everybody loves. Seems like it doesn't come w/ a base. Any differences in use or care for this? Read about Choseras cracking if dried too quickly. Your thoughts, gentlemen?
it's just a name change from naniwa.
Naniwa Professional Stone (New Chosera)
The tighter tollerances probably won't be felt at the 1K end. The 10K end should be marginally better.Quote:
Q. Is this the new version of the Naniwa Chosera stone?
A. Yes, Naniwa changed the name from Chosera to Professional stone. It has always been their professional stone, now its name reflects its intended use. The same method of production that has made this stone famous has merely been updated to allow for tighter standards in grit tolerances.
The stone is still the same binder, and will still have the same care requirements.
After use, let your stone dry naturally, away from any heat source. Keep it out of the summer sun while drying.Quote:

So far so good.
Looks like this one is thinner (20 instead of 25mm). Hopefully the service life is still the same. Wonder if anyone here has used the new ones yet.
Interesting. Both are magnesia bonded stones, the new ones are thinner, 20 vs 25mm, and they are cheaper using the above link vs CKTG for the old ones. One of the biggest complaints about the 1k Chosera as a bevel setter was it's cost, so maybe they just made it thinner and reduced the price? Most companies are pretty sensitive to perceptions of cost.
If I look at the ratios of the thickness I find that 20/25 = 0.8, while the ratio of the prices is 81/95 = 0.85, so the real cost is not much different really.
I have heard some info about the grit being more uniform in the new stones, but that would seem an incremental improvement though it should reduce the "rogue" grit scratches.

New Name .... New Price....the exclusive Seller for Germany told material prizes 20% up....
a 10K Naniwa from the new product line was the last ive seen around 250 USD...so no cheap-ohhh....

Chef knives to go forgot the gemtlemans name that runs the show but is very informative in regards to choseras and is a gentleman. The 5k is a thirsty hone but once u use it alot it slows down.. For the higher grits and price range i would look at the suehiros 10k 15k 20k there just awesome stones .. or for cheaper the naninwa 12k is a great finish stone imo. The suehiro 20k is supposed to be the jnat finish for a synthetic .. imo its become a lil to harsh for me thats only because as u progress in honing u realize what stones produce what feel and how to get there.
Biting the bullet. I'll post how it works when I get it. Also finally joining the Dark Side & getting Shapton GS 4,8,16 as my Norton is officially kaput. Need that 1k for all those barbershop razors.
Came today & lapped it up in 5 min on my well worn DMT 325. Very green, very heavy, very smooth surface after lapping. This should be fun...;)
EDIT: just reset a bevel. Did circles, half strokes & a few other things. Fast, doesn't glaze, fast, great feedback, fast, needed minimal lapping afterward to clean & just to reiterate: fast!
Feedback feels a lot like the GS which I also took on their maiden voyage. Seems very similar in feel albeit slightly harder, making it a natural before the progression. When done on the stone, the razor seems like it wants to stick to the stone & starts chattering. Sharpness tests then reveal a very clean bevel that shaves arm hair effortlessly i.e. a set bevel. There is simply no comparison in feedback w/ the other 1k hones I've used. Glad I finally joined the club!:tameshigiri:
I just got the old version aka the green brick with slurry stone. Can't wait to use it!
There great stones.. Do the new ones have slurry stones
Mine doesn't. Not sure you'd really need it though--just leave the slurry on after lapping w/ your diamond plate.
Speaking of, how long (if @ all) are people soaking these? I'm assuming the new would be like the old one. I've tried splash & go but find it still drinks. I've been just running it under the tap or in a tupperware for 3-5 min max & it works well.
The slurry stone is supposed to be used to clean off swarf, etc between lappings, not just for slurry per se.
The 1k should just b splash and go..Haven't heard anybody soaking the 1k.. if its thirsty it will slow down with use. Keep spraying it heavy water until it stays wet then hone
I just splash amd hone. However ive seen on CKTG that they say a 5 to 10 minute soak will get the best use of it. I dont do it though. I think the drying cycle may cause some issues.
