Language, Use, Tool, Instrument

The 'use' of a saw as a 'tool' or an 'instrument' is as an inert object, by an animate being.  On that basis, to say that one 'uses' one's hand, as a 'tool' or an 'instrument', e. g. to grip and to cut with a saw, is inappropriate.  Likewise inappropriate is to characterize smiling that is an expression of happiness, as a 'use' of a smile to express happiness.  Now, while oral and handwritten speech are immediately and animatedly expressed, the printed word seems, by contrast, inert.  Hence, it is by the misleading example of the latter that Language is characterized as a 'tool' or an 'instrument' that one 'uses', which Wittgenstein fails to discern.
