I'm hoping a 4 stone grit progression will be satisfactory in Shapton glass bench stones. I have all the grits I mentioned in the title for the EP except the 320. I have everything from 500 to 16k in EP stones. But I've always had the feeling using the EP and bench stones there is a big difference in some things. I think the biggest thing is the fact that the EP stones are only 1" wide. With less area contact between stone and edge the lbs per sq in would be more. OTOH, not always is even the entire 1" area on the EP stones actually in contact with the edge because of the curvature of any given blade. I'm saying I don't know if my experience with the EP stones will give me an accurate guess at how the 4 stones I mentioned will work with bench stones. There is one stone skipped in the progression between the stones mentioned. Well, I feel ok with the 4k to 8k but the 320 to 1k and 1k to 4k I'm unsure of. Will I NEED a 500 and/or a 2k as well? Right now I think I'll be fine and will make any final judgements based on my using the stones but I'd still like any input from those familiar with Shapton glass bench stones. This info may help others looking to buy stones and considering these type. Right now I have everything except the 1k. I've already tried the 320 to 4k jump and it's a bit of a leap. I like one or two of my DMT and/or Spyderco stones between 320 and 4k. I'm hoping the 1k will fill the gap acceptably. Anybody know for sure or if they think a 1k is all I will need? I know this is asking for opinions and they may vary but isn't that always the case? Any help is appreciated.
If you are looking at Shapton glass the 320 grit really cuts fast and doesn't wear as fast as I was afraid of. I flattened it when I got it. Funny, those things come with some sort of film on them. Spray water on them and it beads like a waxed car. Anyway, I lapped it and used it enough to wonder if it had dished. I lapped it for about 5 seconds and found most of the surface was being contacted with the lapping stone right away indicating is was still VERY flat. Me happy about this.
Edit: I forgot to add for anyone interested the Spyderco UF and the Shapton glass 4k seem to be very close in performance. When I go from the Spyderco fine to (Spyderco UF or Shapton glass 4k) then to the Shapton glass 8k either of the stones work fine. Just FYI IMO. Actually, going above the Spyderco UF or Shapton 4k is really overkill for most EDC needs. Again, my opinion. Believe it or not, after finishing either stone you can open about any cardboard box anywhere.
