Thread: Naniwa Chosera 400 vs Shapton glass 500 for rough work

Yea, I think we are talking about 2 diffrent things. Bevel setting and repair grinding. Originally when I bought my 400 Chosera it was to do both. It is not suited for repair grinding, or better said there are better choices. It is a bevel maker, which is why it will re set a rough bevel on a knife or razor quickly. Rarely do I need to re grind a bevel to that degree on a razor, without having ground a breadknife edge. So it did not do what I intended when I purchased it.

If you are grinding your own blades and are establishing a brand new bevel you will also be removing a lot of material and alligning the edge. I would use a DMT, Washita or India because they can do both well.

Yes, generally I need something fast, because I have to remove much more metal that in a regular honing sesson, even more than in a heavy restoration job. Imagine that you breadknife a razor so badly in a 90 degree angle, that you don't see a bevel anymore. Now, I have to start with an edge like this Even if I start with 45 degree breadknifing until my bevels meet in the middle, I have a long way to go with 61-62 and up Rockwell razorsteel until I have a bevel I can take to my 1k Chosera.

A 400~ grit stone will be dual purpose for me, because I want to use them on J-knives too. And I will use some pressure with those, so a non diamond one would be preferable

Jeness, what is the chance that you could get a makita wheel grinder - the ones that work flat? That would seem to work a lot better for this purpose, when you're still dimensioning the metal. It would also be good on knives.

Not that it matters much anymore, but I wanted to change my vote to DMT. Ofc I bow to those who've used the other ones. Just had to share my agreement at how well that thing will eat metal. Seems I should have tried it out before.
