"Wait."

He lifts the wing he severed before and shows her the end, touching the still mostly intact knob of the joint.

"Look for the joint. It's the weakest point. Instead of cutting through, push down between the bones."

Otherwise he leaves her to the effort. As for the wings?

"I'm not sure. We'll set them aside for now."

"I suppose we should try to save the fur too."

Tedious, but it'll probably be useful to someone as long as they manage to keep it intact.
