Forget Zwilling. Stick with reputable Japanese brands. Suehiro ouka 3000 and Rika 5000 come with cleaning stones. Chosera 3000 comes with big red 600 grit dressing stone. Medium rust eraser or white china cleaning stones work well. The kind than come with china sharpening sets (not recommended).

I recommend Norton India IB8, if mineral oil is OK; King Deluxe 300 splasher if u prefer water. And a homemade strop or Sharpal strop.

Chisel on traditional stone-n-strop. Durable Norton India IB8 combo oilstone (8x2x1", 150/400 grit, nonfriable), mineral oil (odorless, food and skin safe), and black emery buffing compound on denim jeans strop is great for knives and tools. https://youtu.be/xlwKYeq909g CHEAP and SIMPLE Sharpening System.

Sharpening X50 santoku with King Deluxe 300 [hard splasher, >500+ grit finish, green SiC?] and Sharpal 208H green compound on denim jeans strop. https://youtu.be/Exx1gBguy00 Amazon Knife (1.4116 steel) + King Deluxe 300. Quiet Sharpener : The King 300 is the best bang for your buck whetstone out there. It cuts and leaves a finish closer to a 500 grit and it has the bonus of being splash and go. I strongly recommend this stone to someone starting out.

Flattening stone should be larger and much coarser than water stones. Wet 100 grit SiC sandpaper on glass works too.

I have the 150/400 grit one, but the 120/180 grit one might be better for flattening.
