Levi's been in the medbay and few times and once went through all the drawers and cubbies out of curiosity, so he knows where the scalpels are kept. He pulls one out and looks between it and the husk remaining on SecUnit's arm. These things were sharp and he'd seen Daan do a lot of damage with one, but he had no idea if it had the strength to cut off the husk remains.

What he does know is that SecUnit wouldn't appreciate him just trying so he holds the scalpel out, handle first. "H-here. I've never cut anything like that but I've done some field medicine so, um, I-i dunno. I can try to help, if you want."
