Central texas rock
« on: January 03, 2019, 10:39:54 pm »
This is a rock I got at the knap in. It came from around San Antonio TX
I got a good start on it and was surprised at how well it was working up to the point where I got yellow wristed and knocked a couple plugs out where I needed big overshots and it just kind of went down hill from there.
I finally quit hitting on it after I knocked the base end off twice then used a 3/8" copper rod to straighten it out best I could with indirect percussion then pressure flaked the edges.
Finished up at 5-5/8 inches long and will make a good knife blade that im happy with, but I really intended to make a Caddo blade a good bit wider than this and a little longer too.
here's the rock

and here's the repair job.
The finish on it looks just like a gravel blade.

Nice recovery!  Looks like a fine blade, needs an antler or leg bone handle!

Very nice recovery 1442. I would've liked to watch home you got those two boo boos out. I very much dislike when that happens to me.

Thanks
bjrogg, I just put a bevel with pressure enough to be below center, grind it, then seat the 3/8" copper rod to take a heavy flake while supporting the piece on thick soft leather and nock fire out of the rod real close to the rock. The heavy flakes traveled to the far edge almost and just cut right under the high spots.
I lost most of the width trying to straighten out a curve in the blade.
