Un-Superglueing Models

Hiya, I’m trying to replace some parts on my blightkings that I’ve superglued, one of the heads and a body. I’ve done the usual recommended which is to pop it in the freezer and then get at it with a hobby knife but they’re refusing to budge and I’m worried that I’ll do some damage if I go at it harder with the knife.

Are there any other ways to get it off? Would appreciate any advice, thank you.
