We had throwing spears 400,000 years ago. Blades
go back millions of years, if you want to get
technical.
The last that I heard is that blades started to occur 500 kya, and they became common 300 kya, if I recall correctly.
It's kind of funny how a chimp banging something with a rock
is "a tool" but early Homo (or even pre homo) BREAKING rocks
to produce sharp flakes for cutting isn't a "Blade."
They were sharp and used for cutting!
Put another way: How far back do CUT MARKS go?
Cut marks == blade
No?
I say yes, and your blades go back 3 million years plus, but
some evidence.
It looks like you are confusing something. Not every sharp edge is a blade. Blade tool is only a sickle, there is no other blade tool. Blades have sense only as a sickle.
A "Blade" is a "Tool" with a sharp edge used for cutting.
