I pressure flaked slabs awhile ago, did a lot of grinding to create platforms. Recently I've been getting into the percussion flaking and have enjoyed it tremendously. Your videos are a big help, thank you for sharing your knowledge and experience.
Hi, Jim. I have another question. I hv asked several questions, & you've always shot back good ansrs. Thks. Don't blame you if you get tired of it, though.
Inspired by "Flintknapping Slabs," I bought some slabs & obsidn rcks. One was the shape & thknss as the piece you stared with.
I intend to try to make a 6 - 8" knife blade as a gift for my son. Any reason why I should not cut a 2 " slab off the long side, and save rest?
John, that sounds good to me, might as well get as much as you can out of the slab. I often use a glass/tile cutter to cut slabs, lots faster than the saw.....enjoy...jim
pretty god damn amazing skills. Wonder if you could show some old european techniques, like levallois core method. i know they will be very simple for you, but i think many people would like to see it
The Ishi stick is what allows the flakes to travel much further. It allows the knapper to use both upper and lower body by squeezing the legs to generate much more force. I also add a bit of impulse at the moment of flake release to get the really big flakes....anyone can do it....
Good question. Slabs have no ridges for flakes to follow. Flake removals on slabs should be spaced far enough apart to create ridges between them for the next series of flakes to follow. If flake are too close they overlap too much and dont create ridges. If too far apart flakes fan out and dont travel far. Best is small amount of overlap, maybe 30 or 40% or so, to create strong ridges. The next series of flakes will follow these ridges and travel much further than the first set...jim

all of the small flakes are still razor sharp and you can use them to cut

Where do you bet the obsidian?

Jim, I saw that when you where flaking some of the flakes you struck off where further appart than others. Is there a reason for this?
