By slicing, do you mean cutting an actor in half with a gesture with a finger, like fruit ninja or cut the rope?
If so, I think this is possible. Try:
Always
Create actor "Blade segment" at x of touch, y of touch.
And a behavior for the Blade segment actor:
When created
Do After .2 seconds
Kill Self
Finally, a behavior for the actor to be sliced:
When this collides with something else
Switch animation to sliced
[do other things you want the actor to do when sliced] .
