What is the cheapest option for a stone that would be 15k-20k not using film.
What do you have against film?
Diamond pasted balsa after your best stone?
I’ve been getting 15k plus edges off of $100 Jnat, black ark, trans white ark, coticule. If you go with and can hone on smaller stone it’s more affordable.
No disrespect intended.... learn to max out the stones you have... $ Free dollars.
Having used a 20kg I don’t think there is a big difference to the 12 k Naniwas.
I don’t think film is going anywhere soon, too many industrial uses. With razors pre finished well , and use a light hand on film I can get Conservatively 45 razors honed on 1 full sheet of film. About $2. 1 micron film gets me a 14K+ edge.I dont have anything against film. I just would rather spend some money for a stone that will last for my lifetime than have something I have to keep changing and hope they dont stop making it
I have one of those stones and it works very well.I mean the glass stone seven is like $110usd. You get a surface area and meat similar to a typical coticule but it is splash and go and fast. Might be able to do better if you shop around or buy used
