A no finger stone finish on a knife i've been sharpening for a friend for awhile.

Aoto Finish on a friends takeda

Re sand / etch / force patina / polish on my maumasi

 

Can I send you some of my knives??

 

:Ooooh: that maumasi! Holy sheeeeeeeet

Is that my kato Matus?

 

Just finished touching up a project knife but no camera at the moment.

An older project...working finish on a Carter, before I received some fingerstones:

 

Edit - can see by the handle it must be yours.

 

yes....will i send them back??? maybe.

 

Ah whoops! Apologies. Looks great!

 

this one above is a 180 mm Sujihiki special in White #2 KU from Watanabe.
I first "removed" the black KU finish to mirror, a long job.
I worked a bit on the saya too.

After this basis I polished with a big Uchigumori Hazuya from Ohira, then Hazuya fingerstones and Jizuya fingerstones.(both from Ohira)
I can't rmember wich kind of paste I applied on it at the end, maybe Jitteko.
Hard to see on the picture but the blade has contrast and is extremely glossy and this without mirror effect.
It was the glossiest result I got.

But more to come...

 

Not sure. It was around the time I got my white suita from Shinichi, so that may have been my last stone, but it might have been hakka juice on a burnished binsui base.

Thanks for the compliment.

Fine edge sharpened on an Ao Renge from Ohira. Very beautiful and useful sujihiki.

But more to come with Kintarou Ame, Damascus, Kitaeji and probably a better camera ;-)

 

Sabaki special with engraving and inserted diamond, and Yanagi special, both from Watanabe. The yanagi has been polished with Uchigumori from Watanabe himself.

already beautiful but I'm about to polish them again. Still with fingerstones but mat/mirror glossy.

I love this Gyuto 270, my favourite knife

Thanks Matus, in fact if you take more time than I with a slowly progression and concentrated moves, your results will be much better than mine and this at the first time!
I don't believe that technique plays the biggest role for polishing.

 

Great thread nutmeg!! These have variously been posted under different threads but here goes.

Hinoura on Monzento







Same Hinoura with a King 800 > Monzento > Maruoyama shiro suita > fingerstone finish on the blade road
And a micromesh finish on the blade flat



Red Orca gyuto with a horrible machined on finish that I ground off with coarse stones (I don't recommend it) and refinished up to 1200 grit sandpaper

I was playing with Takamura R2 Mikagi. The main problem was that the spine was really sharp and I needed to round it a bit. So first I did the spine but later noticed that also the bolster is way too sharp for comfortable use. Unfortunately I do not have pics of the part when I was rounding the spine&bolster.

I just documented the polishing that I did yesterday:

I needed to start with very coarse sand paper as the vertical scratches from buffer wheel were really deep:



followed by (BTW 180 is where Heiji stops finishing his blades):











Missing picture for 2000 grit

Later it was time for polishing:


A bit more detail:



Then it was time for finger stones (courtesy of Matus )



Some more detail:



Somehow the tip got lost in the whole process:



The whole process (without rounding spine): rounding of bolster & polishing took me 3 hours. One of the results was also this (on both thumbs):




Now the knife is much, much more pleasant to use. It makes huge difference. In the next days I just need to restore the tip and give it a good sharpening job.

 

Man that makes me miss my Takamura.

 

It was my first time using finger stones and honestly I was a bit disappointed by the result. Most likely you are right about stainless steel.

I was thinking the same about loosing tip. Indeed the only explanation is the it was gone when I was going over it with coarse grit. Nice suggestion about the stop, I would even think that it would be enough to make the stop a little over the edge, so that the middle of the sanding paper would stop at the tip. I will try next time.
But funnily enough until now I never lost the tip when refinishing the knife. I did that with 3 gyutos: Miyabi, Akifusa (2 of them) and 1 Heiji petty and they were all fine. Perhaps the fact that I really used 120 grit paper to start (with others I started with 240) and the fact that it is extremely thin behind the edge.

Great knife, especially now that I fixed the flaws that were making it pretty uncomfortable to use. The only other issue that still exist is unfortunately non fixable = handle. If they would at least come with WA handles. This western handle is a bit too small and you cannot do anything about it.
As we saw some time ago not even WA conversion helps as there is that nasty whole in the tang.

 

Stainless is a point but I think the blade was a bit scratchy for fingerstones.
Some could say fingerstones show the caracter of the blade. It looks more metallic and shows the scratches too as versus to mirror polish.
180 is very rough and removes a lot of steel. You should try starting at higher grain.
Also you were polishing all way parallel to the lengthwise axis of the edge.
Try to start at 45°, then 30°, 15° and after 1000 parallel to he lengthwise axis of the edge. That way you can better control the scratches.

 

to see the scrathes on the blade I take the blade in the direction of a light .







the most difficult is not to polish but to patience until the smallest scratch is gone..!
(I never managed to be patient that long ;-) )

 

Yes indeed I scratched the blade after I used finger stones..

I reallhy needed to start with very coarse paper as the original vertical scratched were very deep. With 320 they would not go out.

I will try next doing an angle with every grit, but this for sure is more difficult and will take more time. I must say that I was pretty happy with my result despite doing all sanding in the same direction.
