My stone hand axe
Let me tell you about my stone hand-axe. I got it from a river bank on the Chilliwack river, I was originally there to make cairns but when I saw the potential in this rock I fell in love. With a well placed center of mass and a comfortable handle, this rock was easily the coolest rock there. "This would make a great axe if we were Neanderthals!" I took a hammer to it and made a decent blade on the side, it isn't sharp, but it can do some damage with a good swing.
The main advantage to this axe over other types of hand axes used in that era is probably the location of the handle; Because it's farther from the center of mass, each swing has additional force.
Compare this with Acheulean hand axes, 
held from the base of the rock, right behind the blade. Such a tool would be less powerful, as it wouldn't have as much leverage behind each swing.
However, my axe also has its disadvantages. I've noticed it to be slower than the hand axes of old, and its blade is much shorter, which makes my axe harder to use. Despite these flaws, I believe that somebody more skilled at knapping would be able to use my axe as a prototype; Creating a sharper, lighter axe that still has a handle placed far from the blade.
Making this hand axe was all about the stone itself, if I hadn't found the perfect rock with a cool handle, then I never would have even tried to make an axe out of it. If you're trying to make your own stone tools to play with, don't try to force your will onto the rock; Instead, you should focus on what the rock WANTS to be. It’s not just an object, but a piece of craftsmanship that, once finished, feels incredibly satisfying to hold; Like you’ve unlocked some truth hidden inside that rock.
That's all for now, goodbye from Sam.
