  Readiness-to-hand has a distinctive phenomenological signature. While engaged in hitch-free skilled activity, Dasein has no conscious experience of the items of equipment in use as independent objects (i.e., as the bearers of determinate properties that exist independently of the Dasein-centred context of action in which the equipmental entity is involved). Thus, while engaged in trouble-free hammering, the skilled carpenter has no conscious recognition of the hammer, the nails, or the work-bench, in the way that one would if one simply stood back and thought about them. Tools-in-use become phenomenologically transparent. Moreover, Heidegger claims, not only are the hammer, nails, and work-bench in this way not part of the engaged carpenter's phenomenal world, neither, in a sense, is the carpenter. The carpenter becomes absorbed in his activity in such a way that he has no awareness of himself as a subject over and against a world of objects. Crucially, it does not follow from this analysis that Dasein's behaviour in such contexts is automatic, in the sense of there being no awareness present at all, but rather that the awareness that is present (what Heidegger calls circumspection) is non-subject-object in form. Phenomenologically speaking, then, there are no subjects and no objects; there is only the experience of the ongoing task (e.g., hammering).
