Ok, 220 to 2k is not advisable. But, adding the 1k seems a little close to the 2k which I already have. Wouldn't I do better by adding a 320 or 500 to the 220 instead of the 1k? Or maybe just getting a 500 instead of the 220 (adding only one instead of two stones)? I've only used the 2k so far. The 6k should be here tomorrow. For one more coarser stone, now I'm thinking the 500 would be best if a jump from 220 to 2k is too great. With the 500, 2k, 6k I could then decide if I want a coarser or a finer grit stone after I see how these three do.
Does this sound like a plan?
I'll be surprised if I want anything finer than the 6k judging by the performance of the 2k. I can eliminate most of any scratch pattern from any stone just by stroking the edge with a parallel stroke with the edge instead of the normal perpendicular stroke. Or maybe a little circular motion (which I don't do) but it's the same theory. On the EP I stroke straight into the edge but before I go to the next finer grit I slide the stone along the edge from heel to tip a few strokes with very little pushing or pulling. This changes the finish tremendously without changing stones.
I doubt if I will ever need a 16k or 30k stone. However, I don't really need these either.
I may want the 220 later if I want a coarser stone than the 500 just to have a set of Shapton Glass stones eliminating the need for the other ones I have. They would always be there for seriously damaged edges or something.
Thanks for your advice guys. If you see any flaw in my thinking please let me know.
