TOPIC: 600 grit diamond ––> microfine ceramic?

600 grit diamond ––> microfine ceramic? 1 year 10 months ago #5256

I'm going to be buying a WEPS soon and was wondering if it is possible to omit the 800/1000 diamond stones from the progression and move directly from the 600 to the ceramic microfine stones. Is that an effective protocol or is the 800/1000 stone necessary? Will the coarse ceramic remove the scratches from the 600 or only smooth over the ridges leaving micro-serrations?

I'm just trying to keep my initial cost down and keep my long-suffering wife from blowing a gasket over my newest fixation.

It will work but you're going to spend a lot more time on the ceramics than you need to if you're really wanting to remove all the 600 scratches. Only a guess. Maybe 800+ strokes? You'll get there (if you don't get carpal tunnel first ;) )

Welcome to the forum!

I did a little test after reading your post. I sharpened a blade, but after the 600g stone, on one side I moved to the 800 --> 1000 --> Micro coarse --> Micro fine. On the other side I substituted the Micro stone for the 800/1000, so I did Micro coarse --> Micro fine --> Micro coarse --> Micro fine. (Guess I could have done Micro coarse twice as long then Micro fine, but I'm not sure it would have made much difference). The end result, I spent twice as long on the Micro stones.... but not a really long time total... just a normal sharpening.

Surprisingly, visually there wasn't really a noticeable difference. Even under a handheld microscope they looked pretty close. But, neither path will really get you to a mirror polish if that what's you're looking for. Both sides had a hazy finish, and you could see scratching.

If I have time later, I'll try to strop both sides with some leather to see what happens. Are you considering leather or other strops? Part of the answer depends on what you're looking for... but sharpening wise, going from a 600g to the MicroFine should leave a sharp edge with a nice "bite" to it.

Also remember the results will improve as the stones break in.

Thanks for the welcome and for your testing. I appreciate it.

I asked the initial question because in a post a while back Clay mentioned a progression where he performed some testing where he went from 600 to microceramic but he didn't report back on the results. He seemed to indicate that the coarse microceramic was pretty aggressive and was able to address the scratch pattern of the 600. He didn't really say definitively, though.

I'm trying to decide which stones to buy in addition to the basic WEPS for finishing. It sounds like I might be better served buying the 800/1000 stones and the 5/3.5 strops instead of investing the same amount of money in the microceramics.

Here's the thing. My coarse micro stones actually feel rougher than the regular ceramics leading me to a progression of 1000->1.4 micron->1200 ceramic -> 1600 ceramic -> .6 micron. Several folks "fixed" this by lapping the 1.4 micron stones on fine plates (> 1200) to make them smoother but (so far) I've left mine as received and just changed the order. It works great (and a few othes around here have done the same.)

If your goal is to remove the scratches of the 600s I still maintain you can do it with the micro fines, but as I mentioned, it's going to take you some time to get there. It's up to you whether the cost savings are better than the time you're going to spend. Probably a better short term goal is to use them to refine the edge a bit but not go for complete removal of the 600 scratchs. As CBW says, you'll still get a very nice edge and in a reasonable amount of time.

It's all a trade off... You can sharpen a totally dull blade with nothing but the .6 micron stones. It may take you 10,000 stokes, but you could do it...

That's another approach with the same caveats. If you are thinking to remove the scratches of the 1000 diamonds with the 5/3.5 micron strops, you have a lot of stropping in your future ;) Not to say you can't get a very nice, usable edge before that but you'll be polishing the scratchs, not removing them. Eventually you'll polish them out but we're talking maybe thousands of strokes. 1000 diamonds will give you a nice edge and 40-50 strokes with the strops will smooth them out quite a bit.

Many folks consider a 1000 edge to be the perfect working edge.

If it were me, I'd start with your first scenario of the micro fines. See what you think of the edge and what it took you to get it and you'll have a better idea of whether you'd rather add 1000 diamonds or strops next. Ultimately, I think you'll want both.
