Well I think Heidegger nowhere wants to, "establish the priority of handiness of things over their objective presence.After introducing the contrast between these two sorts of being( a tool's being and that of an object of observation and/or theory),Heidegger is coy on this question of priority....The coyness is deliberate since the point of his analysis of a tool's sort of being is not to establish it as an independent category of being but to underscore the efficacious absence of the world as what makes the tool (and its inconspicuousness possible)."
