figured i would post a couple more pics i have. i have found one of the hardest things to do is thin. i think i am starting to get the hang of it. I have had trouble not getting the flake to run the length of the ridge. i have found if i put pressure with my hand against the stone when i strike it. the flake will run farther down the ridge. if no pressure it tends to die and fingernail fracture into the stone

it will take a lot of practice and time to learn well. also i have plenty of hobbies

so i play with it of and on. hope you enjoy the pics.
the fist is a strike i used to remove the rough outer cortex left on the stone and give myself a smooth surface to work on.
the second pic is me thinning down a ridge. the flakes are in order they were removed.
