Flint knapping is useless where I am. You have to know how to heat-process orthoquartzite.
Not familiar with that one, but I suspect that it has a similar learning curve, where it’s easy to get started with it, but takes a lot of practice to get good.
Also applicable to plant identification. And an error can kill you.
That is, some things in some areas are easy to identify. Others are less so. And if you have to rely on your memory, a couple of days’ study is likely to leave you in a really risky state of partial knowledge. If you can bring field guides, that would help a lot.
Or better yet if you can bring @MrDibble, or somebody equally knowledgeable, and go to their area.

The dangers of plant foraging are rather overstated. Most inedible plants are inedible simply by virtue of being too tough to eat (at least, for humans). And of those that are actually harmful, most taste really bad. In any given area, there will be a relatively small number of plants, or categories of plants, that you need to learn to avoid. At worst, you’ll end up avoiding some edible plants just because they resemble the bad ones too closely, but that’ll still leave you with plenty of other plants to eat.
Or you just learn the edible ones that are unmistakable, if there are enough of them. That’s especially the case with mushrooms, at least here - there are 4 kinds that don’t have any false friends. Unfortunately 2 of the 4 are not native so wouldn’t be here in the prehistoric past.
But it goes for other plants as well.
