Hello:

I recently purchased a JNat to try and figured it was time to learn how to polish.

I have a couple years of sharpening experience now, albeit low-volume. However, I haven't really owned any non-stainless or wide bevel knives - or any formally Japanese knives for that matter (discounting my tojiro; it was miserably warped and I elected to return it). My daiso nakiri had been my trusted partner for almost 3 years, until I had to leave it behind when I moved a few months ago.

I have been fortunate to have some cooking enthusiast and chef friends who lend me their jp knives to sharpen and use, but now it's time to learn some skills and buy a knife for myself. Kasumi is one of the things I would like to get down before I sink some cash and take the plunge, and that's what this thread is about.

A big thanks to @BillHanna for selling me his knife and to @Forty Ounce for the advice.

Materials:
Cerax 1k
Cerax 3k
Shiro Suita Koppa (unknown mine, maybe 5k - 8k grit?)

I'll add pictures as I go along!

Ok, first came the Cerax 1k. I chose to start on this because the wear on the bevels didn't seem too bad. I figured a few minutes on the stone would tell me if I needed to bring out the sandpaper.

Close of up the old bevel:

First pass on the Cerax 1k:

I was able to get the bevels relatively flat, but there was a small patch near the tip of the knife that was slightly concave. I was making small, light strokes like the video here: http://instagr.am/p/B_PpCckDTml/
I found a few scratches to be quite deep, so I thought I would continue for another couple of passes.

The right side bevel had more scratches on the left. Not sure why. Onward to the 3k.

The Cerax 3k is my absolute favorite stone to use. Technique wise, not much more to share here. The same deep scratches remained, to my dismay.

In any case, here's where it got me:

I'm missing the middle of the bladeroad at the tip. Maybe I'll iron that out one day.

Now the koppa. This was my first time using a JNat, and I spent some good time on it. Tried not to contaminate it with other grits from my synthetic stones, so swapped out all the water, wiping material, and washed my hands.

I really like the renge pattern.

The shinogi line is very uneven, but it doesn't look splotchy in person (I think). The following pictures are more flattering, but I'm including these because it shows the two kireha side by side.

I was pleasantly surprised with the steel. It sharpens quick, and gets very sharp too. Push cuts on a paper towel.
