Thread: Jnat Finishing Routines--what are yours?

1, 5,12 could be a nice progression but I often use 1.5 & 2k as well. I find the 1.5 ,2 & 8 can fit somewhere in there more often than not & the small jumps help keep the stones flat too, useful when doing a handful of wedges which I try to mostly avoid Typically on a razor in good shape 2k is plenty for a light bevel set. Don't be misled by the numbers 1k -1.5k are quite a marked difference like 800 -1200 in the Kings. It is a system of varied uses & the 320 is really cool for eBay monsters too. I just run them under the tap/faucet to lap them then light spray with water in use, very light.
I have no probs lapping with the Atoma 400 & 1200 plates. The stones are very stable & don't warp much at all. In use they keep shape nicely too even when doing multiple blades. Like most ceramics prolonged soaking is a no no as is soap, hot water & temp extremes.

I just tried 6 consecutive razors with this method. The razors were shave ready basically. The results on all six blades were phenomenal. I did the .5 micron diamond on SRD felt and the 5-6 laps on a dry Nakayama Maruichi Asagi I got from old_school several years ago. Then 75 laps on horsebutt. Whew!!! That's a beautiful finish.

Thank you for posting this one. Six consecutive blades is no fluke. It works.

Thanx for the feedback Jerry. I've only recently adopted this & don't find it always repeatable but 6 in a row is good run. I think the razor may dictate outcome a little too but if it's somewhat lacking or as good as you think it can get it's worth a try.

I'd sort of like to get the 2k & even the Atoma 400 as well (worried about the DMT 325 sticking to the 12k), but I don't know if I can swing it, money wise. You can probably avoid removing too much metal on the 1k by keeping the strokes light, right? I think I'm pretty much sold on the pros now!

What do you mean the particles break down in thickness rather than size? Do you mean the slurry gets thinner and the actual grit level never changes?

they split in flakes, like puff pastry for example

Oh, I see. Thanks

Good analogy!

You can do all sorts of things ,even experiment with slurries from BBW's, Coticules etc etc.. The pro's excel with light strokes. Could actually be a bad thing for heavy handed beginners.

I have a shapton 1k pro and love it. I wouldnt hesitate to recommend it

If you use the DMT under running water, you'll have no issues with it. I used a DMT for a while before I wore it out abusing it on other stuff, and only replaced it with the atoma after that.
