Thread: Smoothing surface of finishing hone question

I have 2 finishing hones right now an Oozuku jnat and an extremely hard coticule. I recently lapped the coticule, it was giving really good results but I noticed it wasn't completely flat. I lapped the coticule with a somewhat worn out dmt 325 plate and now I was wanting to smooth out the surface some. To smooth out the surface of the coticule I was thinking of either using a 5k/8k naniwa ss, my midstone jnat,or my thuri bout. I have seen some post where people warn that particles can get lodged into other stone and what not so thought I would ask you guys. Could use 2k sandpaper but I would rather not, just looking for info on using other stones.

Thanks for any help

edit: I do have slurry stone for it, I know it will smooth it out as well over time

I'd say the slurry stone under running water. From what I've read and tried this worked the best for me.

+1 to this, but I get better results going to 600 grit then using the slurry stone under water. I get a better surface keeping the stones vertical, when using the slurry stone under running water.

In my experience this is one of those things that is very stone-dependent. You'll need to try a few different ways of smoothing your own individual stones to see what works best. Some stones are better with no smoothing, some need a rub stone smoothing, some need high grit wet/dry and some need burnishing with hard steel.

I have a tiny ark that I after use for smoothing and slurry generation on hard stones.

dinnermint is correct on the vertical, I forgot. I haven't tried the 600, but will on my next lapping.

Underlined is what I was inclined to suggest. You could smooth the surface with the shank of a large screwdriver. Just don't add a lot of pressure. Another alternative would be to simply hone with it, which will smooth the stone as well.

Lapping paper on a kitchen worktop is what I use.
Sounds like I sold you the one that wasn't lapped yet.

Couldn't be happier with the coticule you sold me. I just used the slurry stone to smooth it out and it seems to have done the trick. Will do some honing later but I am sure it is going to be very nice shave
