you got it down better than i did when i started knapping bottles.

Good job on your first point. None of my first ones looked that good lol.
The more you do, the more sense it will all make. Keep us posted on your progress!

That was just the percussion part but it still needs the flaking. I am building a fiber glass longbow today so I will find time somewhere to ge the ishi stick made.
I percussed a few more last night as well since it was so fast to do.

Here is my modern ishi stick. t6061 hardened aluminum shaft with 1/4 " brass insert and 3 pieces of glass that I bopped and now needs pressure flaking. Was very easy to make. Now how do you crank this thing?

bopping was easy pressure flaking not so much. got to get more glass now
I made an ishi stick, and have not practiced enough with it to be comfortable. I'm still using my small, homemade pressure flaker. It's just a piece of dowel, with a hole drilled in the end and a piece of sharpened ground wire.

Keep safety in mind when knapping.. empty your debris from the pad after every flake! Safety glasses are a MUST HAVE when using percussion... that stuff flies everywhere.

Ouch and good point to remember too.
Ouch! Are you going to be able to save the finger nail? (or is the cut below the fingernail?)
it was a teeny nick, just below the nail. Bled like a stuck hog though. No damage done, just a little battle scar lol.

i just got inspired again to make some too. great job guys all of the pieces look amazing.
The anticipation of death is worse than death itself.
Ouch!
You guys do some nice work, I'll just watch and learn, I think, I'm not sure I have enough blood to survive making a point.
Thats why I went in to service work instead of being a sheet metal guy, all the good sheet matel guy are big, it seems........more blood, I would bleed to death by noon.

If you pay attention and mind the safety rules, you can avoid the blood loss.. Don't be a dummy like me!
Lucky for you, there is no fire required to make points

I vote for another thread as this one is getting pretty long. Might be a good idea to condense it all into a sticky if mods have the time. just my .02$
This piece is purely for decoration. It was so wide and only 1/4" thick, I didn't even try to push flakes all the way across. A little background story on this one: I know a carpenter who hires me to do all his roofing work. I was slack on work and he was slack on help, so he asked me to help him with some windows he was changing out in an old house. There were 3 HUGE picture windows on the front of the house, 8 feet tall and 7 feet wide. Big, heavy, and dangerously sharp. One window was cracked, and they were inefficient (not insulating) so the owner wanted new gas-filled ones. I got to keep all the glass. I told him (the carpenter) I'd make him a point from the glass.
The only place I really thinned it was at the tip, for the nice "tapered" point.
Keep in mind, I had no intention of it being functional. purely something for him to put on his wall next to his trophy bucks and bass.

Glass really needs good support when pressure flaking. I've tried a couple other shards and I keep breaking them into smaller shards haha. As I mentioned before, glass is brittle and doesn't behave the way rocks do, so It's gonna take me some getting used to. It's not very tolerant of mis-strikes when percussing either.
I have a lot of this glass. we cut each window into quarters, so now I have 12 pieces about 3' x '3. If anyone would like to try some, I'm happy to share! I can cut them with a modern glass-cutter into blanks, and send a few. If you'd like to make a donation to the DOC in exchange for some glass that would be great!
after working more with glass, I'm learning a few things about finesse. Make sure you set up your platforms properly, make sure you support the piece well, and for your own sake, wear shoes and safety glasses!

Every good point requires a little "blood sacrifice"!Originally Posted by your_comforting_company
Seriously, though, even the tiniest puncture or cut from the tiniest splinter of glass, obsidian, or similar material will produce a ridiculous amount of blood. I'm not sure why that is - maybe it cuts so cleanly the blood can't clot fast enough to get the bleeding stopped before it gushes. Hmmm ...
Preach It - Teach It - LIVE IT
I believe I have the issues of my poor pressure flaking figured out. I believe I was supporting the piece too much and the back face was resting against the pad so that the flake could not travel.
Going to build some pads and see it that helps.
In that picture I posted of my tools, a few posts back, there is a small black rectangle. It is a piece of thick rubber (a piece of tire would work) with a deep groove cut into it. For smaller pieces, you can rest the entire piece on the pad and pressure flake above the groove (gives the flakes a place to go). Pretty simple to make, and goodness knows there are enough tires discarded to cut a small scrap.
