That is a great tool. The richness of the chert/flint deposits in Texas is cool, a piece like that would have been reworked multiple times (by the same group, or later groups) in some of the lithic poor areas of the US.
I used to hunt a Hornstone quarry in Southern Indiana and there were more flint knappers that hunted the site looking for spalls they could work than relic collectors.
Good to hear from ya buddy........To me it seems to be a big multi-tool....Scrapeing edge,cutting edge,and one part with many stacks.So also chopper mayhaps.
