Actually, only the 4K side requires soaking before use. If you want to use the 8K side you just need to sprinkle it with some water. You are correct that you will need to lap the Norton occasionally, but it is very easy and can be done with sandpaper and a flat surface. If you need to lap your Spyderco, let me tell you, it's no fun. Mine was not perfectly flat so I have been working on it with a DMT diamond plate. I'm getting closer, but it is taking forever to get there.
I don't know how the combo of the Fine and Ultra Fine would work, as I only have the Ultra Fine. I'm certain it would work, but it may not be a very efficient method, given the jump in grit levels between the two.
As a point of reference, I am not a highly experienced honemeister, as many on this forum are. In fact, my goal was just as you stated. I wanted to be able to keep "shave ready" razors in close to top form for my own use. What is working for me at the present is the Norton 4/8, coticule and some pastes. I have some other stuff that I am playing around with, and my interest in honing has expanded somewhat, but that's about all I need to satisfy my original goal. If you want to have a go with the Spydercos, I encourage you to do so. Gathering your own experience is a big part of the enjoyment of straight shaving and you will be expanding the data base as you work out your own approach.

Also, remember to wear a respirator if you're gonna lap a Spyderco. The dust is NOT GOOD!
The combo is fine but be aware, per Sal Glesser (Spyderco) the two are actually the same material. The differences are in firing and finishing. The bottom line here is if you lap a F you pretty much wind up with a UF. There have been tons of counter opinions on this but this is straight from Sal and since they are his baby, I'd trust him on it.
If you want to use a Spyderco F, make sure it's flat. If it isn't, return it for a flat one.
+1 I use the Spyderco med, F & UF on mine. They work great but, as Bill indicated, the UF is pretty slow if you need to do much.
Good luck and enjoy!

The Spyderco F and UF are distinctly different. Both before and after lapping. Tap both hones and hear the difference in density.
My results after 70+ hours of lapping and testing them (including the medium hone).

Okay Steven, I'll buy the density is different and I misspoke saying they were identical. They use the same size grit in different binders:

Specifically read posts 6 & 27 (where Sal says he turned his F into a UF by lapping it). He did not say the carriers were the same, but the efficacy was.
Sorry for the confusion.

I'll know soon....
Well I just jumped in (today) and ordered the medium, fine and ultra-fine Spyderco stones. I had been flip-flopping for some time on this but finally got SWMBO to agree!
These will be my primary tools for razors and I opted to get the medium as well to use for setting/refining a bevel. I am guessing I will need something more agressive than the meduim to initially set a rough bevel on a really bad resto piece but we'll see. I would think a piece of wet/dry sandpaper on a glass plate would work if the bevel is really that bad.
I'm hoping they arrive before the weekend. If they do, I have razors in various states of "sharp" and will report back. My intent is to try them right out of the box w/o lapping to see how they are except for the meduim.

Congrats, I think you'll like 'em.
Did you order the 302UF or the new 306UF?? I have a 302 but the size of the 306 is IMO better for razors.... I'm guessing I'll get a 306 one of these days.

If a Fine could be turned into an Ultra-fine by simply lapping it, then you may be certain that Spyderco would not use a different manufacturing process for them. Especially since they already lap the UF in manufacture.
My previous link is to my previous post about how you will get a different finish and cutting rate from those hones when lapped on an identical diamond plate. Tested and repeatable results. Test it yourself.
A different density and a different binder and a different firing process does indeed result in a different cutting ability, regardless of surface finish. You could cut 1/8" grooves 1/8" deep across a Fine or an Ultra-fine hone to give them a massive change in surface finish. They would both continue to give a finish identical to one without such a change.

No doubt, but I do wonder what the comparative results would be... For example (and yes, I do understand Spyderco does not use grit size but just for discussion):
Let's say a Medium - unlapped would yield an edge we could compare to one done on a 600 grit hone, a Fine one that would compare to a 2000 grit and a UF to one on 10000 grit
But once lapped the numbers change upward to Med - 800 grit, Fine - 8000 grit and UF - 12000. Now the effective grit of the Fine stone is becoming comparable to the stock UF..... This is all purely conjecture, trying to correlate your findings with the various things Sal has said about these ceramics. I do tend to trust Sal when he speaks of such things (and they are WAY beyond my ability to prove or disprove)
I read your results. Very interesting. While I am able to lap the Fine stone, I really have no analytical way to evaluate either the surface of the stone nor the edge produced on it. Perhaps this is something Mr. Zowada would want to undertake (in his spare time)??? I would be very interested to see a series of edges on an unlapped Fine compared to those produced on a lapped Fine as, per Sal, I seriously doubt they would be the same. But perhaps they would? Is that your position?
I'm not sure I concur with that but I really can't dispute it either. It seems that such grooves would not impact the surface at all (save to reduce it). I'd consider a surface finish change to be less severe and more pervasive.

I have read a number if reports from folks (including Sal from Spyderco) about lapping a fine to make it a UF. I noticed his (Sal's) post reguarding this stated he did this BEFORE the UF was developed and released.
That is my point; why would a company offer a more expensive version of the same thing (the UF) knowing full well folks could purchase the cheaper (the fine) and get the same results. Spyderco produces nice items from my experience and they are not stupid.
Based on the various information I have read when researching these, I would expect each of these stones to be slightly finer ("grit" wise for reference) after lapping, but I would think it is a function of a smoother, more uniform surface. Again, this guess has no factual basis but makes sense from all that I have found and read.
Again, I hope these do not require lapping. If they do, I will be begging someone here to borrow a DMT to lap them since I would guess sand paper would be useless!
