Creating Cones to make a Thorn/Barbed Wire effect

Hey there I’m new to 3D sculpting, I am currently trying to create a Penitent One helmet from blasphemous using the basic male bust on the app. I’ll drop an image on how it’s going so far. My big question is: Is there an easier way to make cones? To shape the head I cut a sphere then smoothed it out. But I need to make more tiny cones to make the barb wire effect. Making tiny spheres and cutting each one seems like my only option since I tried the Pinch option and it doesn’t seem to create tiny cones.

Any help/advice would be greatly appreciated!
