Fine cuts between curved surfaces call for special tools. Kemper Mini Finger Tools were designed to separate fingers in porcelain dolls before firing, but are useful for many other forms of modelling.
They work best on softer materials, plastic, resin, polymer clay or unfired clay. Their needle shaped blades can work in very tight spaces where it may be hard to use regular saws or jewellers saws.

Those little finger tools look exactly like the tiny finger drills that dentists use when doing root canals. I bet they would make excellent substitutes, if your dentist was willing to give you one!
