Steep steps
« on: November 22, 2020, 11:44:10 am »
I keep getting steep steps on both sides of the point, making the edge more like a wedge than a blade. What am I doing wrong and how do I fix that?

If you are getting steps there are several things that can cause it.

1 your edge or platform even material isnít strong enough. It wonít transfer the shock wave without breaking and stepping.

2 your angle is to steep. It isnít possible for flake to travel completely through spall so it dives in or steps.

3 your just plain not hitting it hard enough. This can be hard and a bit scary to do.

Other things can be really rough tool that causes to many contact points the initiating multiple Weak flakes.

Sleek, here is a few things that have worked for me
1. Are platforms center or better yet slightly below?
2. make sure the platform is ground and strong.
3. this one took me along time to do just because I was lazy, take time to set up good isolated platforms and don't be shy. HIT IT hard.
Hope this helps, Bob :-T
