Been refreshing my razors by using the paste on the canvas strop. This has been working well. No issues. I would like to buy a stone for more aggressive refreshes in the future. Thinking of buying off Ebay:
1. Naniwa SP491 12000 Grit Honing Stone by Naniwa
2. Steelex D1091 Sharpening Stone Holder by Steelex
3. Norton Flattening Stone for Waterstones, 3/4" x 3" x 9" in plastic case

Any comments of suggestions to the list? I am sure there are lots of opinions. I just want to make sure I am not making any big mistakes.

thanks
