Pretty sweet vids you've got on the tube Keith! How many stones do you have...?

Ty, but honestly - my production and editing skills leave much to be desired.
I think in stills - not motion. Can't help it, that's just how I 'see' and 'think'.
Hones - honestly - I don't count.

Neat video, why are you using so little length of your stone though?
Those underwater mined japanese stones seem to be turning up a lot lately, but not many people have much to say about them. What was your impression of the stone itself (not used on the Naniwa)? Or do you only have the nagura?

1.) Don't need the whole stone for what I was doing
2.) Easier to control pressure on shorter strokes
3.) That's what fits in the viewfinder. It's a 20mm fixed focal length lens and the camera is right at the end of the stone.
4.) I kinda like the perspective.
I've been using Tsushima Black for a while - I've had many full size stones, still have one.
I use the smaller Nagura often - it's a nice mood changer to have around. It's gentle on steel and a bit slow but not terribly so.
The slurry refines nicely, I like using it on a hard finisher too.
This last bunch of Tsushima Black Toishi were extremely hard. That small one in the vid is so hard it's not funny.
I can finish on the one I have (the full size stone) and shave well.
Going to a favored finisher afterwards is the usual route though.
There's a few spins that I do with that stone that I really enjoy.

Thanks for the vid. Is it safe to assume that that's the kind of music you're listening to while honing? ;-)

Actually - most of the time, I don't listen to music when I'm honing.
I listen to south park. It improves my edges through work-funnying.
Very interesting. I never thought to use my Tsushima Black on anything other than a JNAT...And I never though to use slurry on the Snow White... I'll have to give this a try! Thank you!!

Like your choice of music on your vids - Lucretia My Reflection is one of my favorite tunes!
Great vids and really nice rocks!

Ty - Big SOM fan here.
Slurrying stones over 3k seems to be counterproductive. In other words, I wouldn't use a DMT to raise slurry on the Snow White. The slurry from the TB seems to have an interesting and positive effect though.
Is it just a visual thing or did it actually increase the cutting power?
I've never used a snow white but I've read a lot and heard guys saying that swarf can be created after a single pass. Perhaps this is just the swarf suspended with the slurry rather than just settling on the stone/infiltrating the honing surface?

Generally - when I use the SW on its own, the stone pretty much stays white. I might get a grey streak here/there.
IMO - significant swarf on the first few passes on an 8k means the previous step wasn't done to completion.
As for what the actual story here is - all I can say it the edge was bumped a good distance past where it would have been without the TB.
I can just about eek out a tolerable shave on an 8k SS and I get a hair better with the SW but ATG still won't be great.
The shave off the blade in this video was very very good with a really nice ATG pass.

I use my left hand as a guide or for pivoting, there's no pessure. Mostly it's my thumb making contact at the back of the spine.
When I roll the blade, sometimes I use the indiex finger as a govenor.

Gotta say I was pretty interested in the video at around 0:49-0:50. There, the slurry shows just the faintest grey presence of the black stone. Following the first pass, one can see trails of swarf on the stone's surface from the start. From there, swarf continues to develop and be held in suspension.

I use for blades that need a bit of correction both hands with pressure, a heel leading half stroke(bevel set stage and decreasing pressure until almost no pressure). Warped blades that need some see sawing to get the heel to toe without honing it flat. (gold dollars are a lot like that) among others. IMO it works quite well.

Generally - the TB slurry does seem to hold particles in suspsension very well, more and more as it gets worked.
In this scenario - it also kicks up some from the stone. Normally - that's a distraction. Here - I ponder whether or not those white particles are helping the black particles break up. I can only guess.
The one thing that these clips can't 'show' is the feedback - throughout, you can feel the edge coming up quite clearly.
Way more than you'd expect, alarmingly so. You can also feel the slurry become increasingly more 'silky' if you put a drop on your fingertips and move it around.
By no means was this experiment anything that anyone ever needs to do. It was something I wanted to get a handle on for a long time though. The first few attempts came up short - I could tell on the stone that those edges weren't 'there.
Reason - I kept holding back on the stone because of my experiences with extended laps on finishers.
Question regarding the slurry thickness/consistency: Is the thickness of the slurry you made in the video the same as if you were using a JNAT? Or does it vary from blade to blade? The reason I ask is because a lot of times I will use a much thicker/muddier slurry when honing with Mikawa Nagura or TB...
Lately, my edges have been a bit "hit or miss" on JNAT, and I am just wondering if my slurry being too thick is part of the problem...Maybe I will try thinning out my slurry a bit and use a little more water...
