Well ofcourse not x) But I will still have tools all around me. The branches and stones can be crafted to become makeshift spears, and smaller knives the like. My biggest problem would be to make fire, but I don't need matches to conjur that, just time and patience, and some trying and failure x) And to find a shelter wouldn't be hard, the trees can be used for a lot. Yet it would be a struggle to surivive yes, even with self crafted tools, but they greatly improve my chances of survival.
If I was all my self and didn't know basic surivial skills I'd be dead after the frist day. If I was to not use basic tools at all, most humans in general would have had little chances in the wild, but still by help of the most primitive of stone and branch tools we escaped near extingtion. Tools isn't the always the fancy stuff, like conventional knives and out-door cooking kits, it is also the tools which made humans famous, forexample the stone knife or the wooden spear.
