With her hands

Delicately, Kasha gripped the shaft and tried pulling it. There was a bit of give, but it wasn't as simple as pulling on it.

Able to feel the mechanisms inside as she moved it, it became clear that they were complex and would require a precise series of actions to activate the mechanism.
