Perhaps these are just different points along a continuum-- all tools (and limbs) are integrated into the body schema to varying degrees. Consider that dancers learn to exert far more exquisite control over their movements than most people do. Another example: a large portion of strength training gains are not simply due to muscle hypertrophy, but to the motor system learning how to recruit the muscles in more coordinated and controlled ways. Edit: On re-read, it looks like we are agreeing with each other. :-)
