How not to make a LeCroy

[GlisGlis]

Thanx Zuma and others
Seeing also you good knappers have this kind of issues partially give me comfort
My knapping routine seems to end almost ever in a pile of grit and dust with occasional artistic sprinkle of blood 
Today I was wondering about the swears used in ancient times.
You are in great necessity of a good blade, miles and miles away of knappable stones, sourrounded by vicious wild beast.
you are knapping your last piece of chert and suddendly CRAAAK .... ##@?@#!!!!

feel free to suggest some
It's archeology after all

If it wasn't for the gravel there would be no sand on the beach.
Here are a few of my classic abo artifact failures. I actually found
one the size of my open hand 40-50 yards off of the river bank while
diving . I could hear his/her shout when it was pitched.
It will all get better the harder you try and listen and watch.
No fun getting there all at once. Think of it as a journey Glis.
One I am still on.
