If you need a tool for round shapes, this one is quite good:

No, I use this idea already.
I mean really the bevel to my red lines
Nah sorry.
hmmm, getting a completely round shape isn’t really possible, it’s always gonna be edgy like that.
I wish I could help further, but I think this is as far as chisels will take you 
I get why you want circles. . it would be good for some of the sci fi stuff I have worked on also. I have just had to accept the limitations with chisels. I just design more squared off fountains. I will chisel some slopes in to make it a little smoother.

This looks very great.
But it’s to huge for my garden 
The top middle yes. . it is just the stone chisel. The two sides. . not that I have ever seen.
there might be an alternative for yours. . I am thinking about it
yeah is it still an octagon ish, but within the game limitations, that might be the best you can do.
Yeah I know it’s a octagon, everybody has sad that a circle isn’t possible: This is the best possibility.
At least being able to chisel it to half a block thickness makes it a little more refined and not feel clunky.
I know it is not a circle, but I think it looks nice
