Gee, you really don't get anything. Why you are in this group at all, if you don't even try to know something? What is "millions of years old"?
BTW, those sickles resemble blades, instead of having multiple micro-blades, you can have one long blade. For those micro-blades to fit into this handle, you got to have a glue. So those sickles were possible only after you figure out how to make good glue, before that you only had the option of using a blade tool.

Yes, exactly. So why would you need to make a blade? *Blade is long and narrow*. A toll is categorized as "blade" if it is twice as long as it is wide. So, blades are fragile, and they don't withstand strong forces.
