has anyone tried both SP1k and SG500 and could compare them?
I have the SG500 and understand they might be close in grit and speed (SG finishes a bit finer, like 600, and SP a bit coarser like 800?)
@cotedupy would be interesting to hear your thought on SP1k vs. SP1.5k
I’ll do ya an in-depth, side by side comparison of these in the next coupla days.

nice! please do. I really like my SG500 but I would love to see how it compare to these others...
That ought to be interesting.
I haven't even tried the others and just traded my SG500 for a double-thick SG500 . I guess I did it right then lol.TBH I can tell you right now, even before my little experiment, that your SG500 is irreplaceable. Except obviously by your next SG500 at some point in the future, when that one runs out . Everybody should have one!
Will be interesting to re-acquaint myself with the SG1k and SP1.5K, neither of which I've used very much, and not for a long time. (Those two stones aren't mine - I've borrowed them from work).
Dang did you also pick these up during a stroll through your local forest?I’ll do ya an in-depth, side by side comparison of these in the next coupla days.

holy sh**t. love these old cotis full of character. too small for knife use?Haha! No the SG500 I had already, the others I found in a railway arch...
We use, and sell, the SPs at the place I work, and then there's another big box of random dirty stones which I decided to clean up yesterday to see what they were. SG1k was in there, along with some other fun stuff; Rozsutec, Natsuya, very nice Tomae (I think) jnat, and one of the most beautiful coticules I've ever seen.
Unfortunately it was very small, but this is a really gorgeous pink coti, with manganese lines and dendrites:

Shhh. It is. I'll make sure to dispose of it correctly. And by "dispose", I mean use it in hand for sharpening.Not too small for knives, IMO (send it here...)
Long time ago. As I said, to me it was the polisher of the SPs mid grits trio. The 1K the sharpener and 2K a super good stone for deburring, stropping, touching up.Yeah, should be fun!
I was interested to see you say above that you really liked the SP1.5K. Because generally I tend to agree with your tastes / opinions regarding stones, but the only time I've used the SP1.5 before - I really didn't get along with it.
Any tips for use...? Or things you think it's particularly good for...?
This is the stone that I recommend to people who are getting into sharpening, it is significantly faster than King 1K, and easy to use, for new sharpeners it is very important to build some confidence which this stone does greatly. It is coarser than other Japanese 1K but doesn't really matter for a working edge. Just don't buy the common SP 1K + 5k combo, I really really don't like their 5K.
The SP1000 is a great candidate for "only 1 stone" conversations.
Very easy to use, quick to produce a burr ( if the edge is not too damaged ), and can finish a Kitchen knife to a very acceptable level of shaving sharpness with bite very quickly.
I always have one in my Fridge.

It’s hard, no feedback, the edge it gives is mediocre.Why do you not like their 5K? This is one that had my interest particularly.

Sp5k is a special animal. Learned to love it… but then it was easily superseeded by the Morihei 4K.
The 4K likes a short soak or at least a thorough rinsing of all sides before use. It’s not forced and it changes very little but that it seems less welcoming otherwise.Got a Morihei 500 in a couple of days ago. I think I need to soak it for a few minutes next time I use it. Either that or coarse stones are just another ballgame! I was attempting to thin down a Global I’ve practiced on a bit too much…

Is there any meaningful difference between the pro vs glass 1k?

All I can tell you is to look at how it dries… A bit like SP320 there in behavior compared to sp1k or 2k, and just likewise the 320 it glazes and is rather thirsty. A short soak don’t do them bad IMO.
Yep, this very directly mirrors my experience and opinion. FWIW. my go to progression these days (depending on how coarse I need to start) is the Shapton Pro #320, Shapton Pro #1000, Suehiro Debado MD-100, Ai-Iwatani J-nat, finishing with the Shapton Pro 12k for a very nice micro-bevel. I pretty much always forego my Shapton Pro #5000. As others have pointed out, it gives very minimal feedback and just doesn't seem to fit well into my sharpening style and needs. The Shapton Pro 12k however, offers really good feedback and leaves a very bitey edge, IMHO.I could get decent results from the SP5K, but the feel of it was awful. I have the SP12K and its feedback is better.
The SP320 was pretty fast for sharpening. Would work especially well with SS steels. Quite well behaved there at that if soaked a few minutes. It was painfully slow in thinning however, would tend to clog, required more water than its speed could ever compensate for.Ah interesting. I actually tried the 320 yesterday for the first time too, and didn't really like that for basically the same reason I didn't like the 1.5k. Sounds like I shall have to try soaking them a little.
I was a little surprised I didn't like the 320, because I love the fast n muddy 220, but that's a very different beast it seems. As you say - the 320 feels like it's of the same ilk as the 1.5.
Interesting, I had a feeling the Shapton 320 stones would be good for sharpening SS. I find the SG500 too slow to sharpen cheap stainless and I hate using the SG220 on edges.The SP320 was pretty fast for sharpening. Would work especially well with SS steels. Quite well behaved there at that if soaked a few minutes. It was painfully slow in thinning however, would tend to clog, required more water than its speed could ever compensate for.
In comparison the SG320 is slower overall, but it's very much like SG500 in general behavior. So in the end it is faster: no need to soak, no need for much water, no need to fuss over. If used in polishing the tidier scratch pattern also saves a lot of time as well.
Being quite finer, I cannot recall that the SP1500 was as "difficult" as the SP320, nowhere near. However in direct comparison with its two sisters, it's nothing like the 1K or 2K. Its general behavior with water, and how slowly and unevenly it dried, and more immediate "muddiness", was much more akin with the 320 than the upper grits.
