Thats great Chad. I am sure you will get it, just like you blazed your test. They will pick the best person for the job, and if tehy know whats good for them, It should be you. Good Luck!
Long story short, you start with a certain type of rock like flint. Glass breaks by the same "rules" as well. You strike the rock and knock off flakes and remove what isn't an arrowhead. If you have a bored spare minute go to utube and search flintknapping. If you watch part of one of them you will get the idea.
