Rotation of a body in free space.

It's been a while since my last physics class. I have been doing some
research into rotation and torque, but it all assumes the axis of
rotation is fixed, that is it rotates freely, but it doesn't move
linearly in 3D space. I want to model the proper Newtonian movement
of a object that has a moment of inertia, but is not fixed in space.
As an example of what I'm trying to illustrate: An astronaut in orbit
taps one end of a free floating wrench. It's going to spin, sure.
But it won't spin in place. It'll spin away. What subjects do I need
to research to find at least a Newtonian level of modeling?
By Newtonian, I mean not requiring tensors. Vectors are fine (even
though I know vectors hadn't been invented when Newton was breathing).
I learned about and remember vectors. I never learned about tensors.
