Shapton K0711 Blade, Murasaki 30000 Mirror Finish Grind

Q: If I have a 20000 shapton for straight edge, would this make a noticeable difference?

I had a friend who had this very same shapton 30,000 grit stone and I liked very much as you can use this for not only extremely minor sharpening for edge refinement, but also for stropping your blade regardless if you're sharpening knives or straight razors. Then I ordered mine from Amazon and unfortunately the stone I ordered never came, and to be honest, I have some Japanese Natural stones and some American Arkansas stones like Arkansas Black and Translucent can do the same job except they're not going to polish a blade as good as the shapton 30,000 grit which gives a blade an almost true mirror finish.

Q: Why is the 30000 grit so much more expensive than all of the others?

With synthetic stones, the finer the grit, the more expensive because 1) there is more material per volume and 2) they may take a little more "work" to produce. Since I do not know that manufacturing process #2 is a well educated guess. #1 is a fact. Hope this helps.

Q: Can these be used to sharpen katanas? If so, which grit is recommended? I know nothing about stones and sharpening blades. Thank u for ur time&help.

These could be used to sharpen katanas, but if you've never used wet stones before, you'll wanna practice on something like a knife to get started. Additionally, you'll likely need multiple stones depending on the condition of your blade and how sharp you want it to be. I use 7 stones just to sharpen one of my wooden chisels. I start with an 80 grit to remove major defects and work up to about 10000 grit. At the very end I finish sharpening with a jewelers rouge, which ultimately leaves the blade very sharp with a mirror polish. If you wanna see more detail, check Paul Sellers "How to sharpen a chisel" on YouTube. That should get you better tuned for what you're trying to accomplish. Cheers!

Q: What lapping plate should i use to flatten the waterstones purple #30000?

I just use an EZE-lap lapping plate. A broken in DMT 328 or just about any other diamond plate would work.
