Thread: Help with Jnat and Naguras

People seem to suggest 325 (coarse) for flattening and something higher for smoothing it out.

Others have more experience than I. I have used a Norton 4k to lap an Ohira jnat after my DMT xcoarse (220) which worked well. I can't recall whether I did the Shuobu.

Take a look at the 140 diamond plate from Chefs Knives to Go, for 30 dollars. It is a great flattening plate, once flat, Wet and Dry will polish easily and quickly.

But, I too would recommend a synthetic for a first finish stone, a 12K Super Stone will keep you shaving for a long, long time, and is much more foolproof to use.

That is a multi-tiered question. I prefer Atoma to DMT for stone lapping but vice versa for any actual sharpening work (though I only use my DMT plates for knives). If you need to lap severely dished or rough cut stones you'll want something more in the 140 grit area, - though actually I prefer loose grit lapping for this work - but for maintenance lapping once stones are flat a 400 is better. For slurry raising I prefer 1200.

Thanx again.

This gives me something to think about.
A finishing stone to start with is a good idea.

Has anyone experience with Shaptons? I can buy a 12000 or a 16000 gritt in the Netherlands. Don't know wich one is better for finishing.

I believe you don't have to flatten Shaptons or am I wrong guys?

You do need to flatten any stone you get. Regardless of company. It's not a good idea to ruin a few edges just because your stone isn't flat.
And, if you haven't yet, check out this site Which waterstone should I choose?
The prices aren't bad, and it's from Germany.

Thanx that's very usefull information.
