Thread: Jnat Finisher honing with Water Only

I guess what we are looking for is just the perfect mix of very fine abrasive particles together with something that will buffer them and cushion the steel against the stone.

I for one haven't tried "tons of them", i wish... But hey, I'm only a stones throw away!

Indeed you are Lemur, indeed you are.

You should join one of our gatherings someday.
We are quite the active group here in and around Oslo, and we seem to meet up a few times a year.
We started what we called "Nordic RazorCon" last summer, and we will repeat that this coming summer as well

I'll see about that, got some bad cash flow... It flows all right but only in the wrong direction!
But should you ever come by Gotland I'll show you the best Jnats in the world, well best at my place at least, that is if you don't bring any!

When I use Jnats I use a prepolisher with mejiro nagura to prep the edge to move to a finisher.
On a finisher most of the time I use tomonagura slurry dilution and finish on water with a few strokes.
Not all finishers are equal, some are more aggressive, some are less, some are softer some are very very hard.
Some finishers may allow to finish on water only, but I personally have not seen many, most are good with slurry and dilution.
It is very important to have the correct tomonagura for the finishing stone, not any piece of Jnat will work well, in general the tomonagura has to be softer than the base stone, also almost as fine even finer if possible, and the slurry should be able to break down fast. In my opinion a good tomonagura is a soft very fine stone. The really hard tomonaguras are just a waste of time and money.

What about tomonagura that is a piece chipped off the same stone?

It will depend on the stone, you can always use well used diamond plate to raise slurry.

Well said, no harm is trying the diamond plate, better if it is slightly worn down but any plate in the #600 or #1200 range is fine.
Good luck and Happy Holidays,
