I need a LOT of them for a build, but there is currently no way to make or find them without visiting a stronghold. Even if you just add a trade-o-mat near spawn for exchanging stone bricks for chiseled stone bricks, I'd be fine with that. I could also use it to make a nice spawn building, if that's wanted. I can upload images of the style I'm looking at. And all the blocks that look like this: Require 5/9 of a chiseled stone block each.
