These are carbide and "sharp", but not "sharp-sharp", will make one bleed and feel it but not just bleed and not realize it. 
Just have to see, but now I'm thinking I can find other cutters to fit the tool if these are not up to the task
I am really interested to hear about what you find out.

It’d also be interesting to find someone who owns a Cricut cutting machine to see how well it copes with circles.
That sounds like another great option.
