Presseure flaking

(1/2) > >>

Ryan Jacob:
So up till now, Ive only used direct percussion. I want to start making some nicer stuff. This would entail using pressure. So I tried it but with little success. How do I get the flakes to travel across the face? How does the angle of the platform entail how you apply pressure ???

aaron:
part of it is having a nice rounded  lens-shaped cross section
part of it is having the flake follow a ridge
part of it is having nice isolated platforms slightly below center.
part of it is pressing really hard- an ishi stick helps
show us some pics of your tools and a piece youre working on
I really hate pressure flaking- percussion is king!

It always kinda baffles me when people don’t see percussion and pressure as equally needed when making points.  I’d even argue pressure is the more important of the two for a point that’s worth anything but I’ve seen a bunch of guys just keep banging and breaking rock.

I see pressure as critical, myself.  Anyhow...2 cents. :)

I broke the piece (bottle glass) but my tools is just a raw aluminum rod, about 1/4 inch thick. I’m still working on making an ishi stick.

I’ll check it out. Thanks.

I know. I just never got that good at both. Percussion gives me step fractures if using tough stone and pressure doesn’t travel too far. I’d like to get better at both
