So, you get stranded somewhere after a disaster, all of your best intentions and planning are somehow stymied. You are separated from your equipment
and modern resources and need tools and weapons.
So you need to rely on some skills and improvise....
You could look for rocks that you could make what you need from, and if you are skilled and experienced - or lucky, that will possibly save your
But say you cant find the right rocks - plenty of places are many days walk from Flint or Obsidian for example. So no sharp edges there.
Well of you are lucky enough to come across some bamboo, you've solved your problem.
Bamboo can be made into excellent blades that are simple to make, surprisingly durable and extremely effective. Indeed, i believe that much of China
never developed a complex knapped stone tool technology in prehistory as the presence of Bamboo meant that they actually didn't need to.
Here are some Bamboo knives that i made a few years back (and posted elsewhere too), from a strip of dry bamboo that i found in a skip/dumpster - yes
i rummage through rubbish looking for interesting stuff that i can use to make things
Firstly a group pic - Cthulhu is for scale. He's not full sized.
This one i designed for slicing meat. The sharp, curved edge works raw flesh very easily:
An ergonomic modern design:
A slim dagger:
And a much broader, longer dagger:
You could simply use a rock to break through the base a large individual shoot (i estimate these came from a piece of at least 4 inches in diameter),
and then split lengthways into strips, again using a rock.
Then just smooth/scrape away on the inner wall to establish the grind/bevel/knife edge - there should be no need to work the outer surface, the curve
of the piece will work to provide the bevel/grind etc on this side.
It's really that simple.
Now i made mine with steel knives and files in a matter of minutes, but i have seen it done with sharp flakes of rock and it doesn't take a whole lot
The edges are sharp enough to slash fairly unpleasantly, and they cut joints of meat cleanly, but it's the pointy end that is most impressive.
This took no effort:
The blood of my Foe! I think i shall call this blade "Bean's Bane"
Of course, now you are thinking "Ooooh, i could make me a bloody nasty spear with this stuff". Indeedy you could!
This aint mine, but when i finally remember to get me some more of this stuff, i'm so making one!

Now go kill some tincans!
