Here are some photos of my artifacts from various places. These are original tools that were used in day to day, life or death, survival. I replicate some of these styles and use the tools experimentally on wood, bone, antler, etc. Even though some of them are broken they were still usable. I would imagine they weren't thrown away until completely worn out.
This first photo is of a knife from near Denver, Colorado. Its made from petrified wood.
This is a photo of a small knife or scraper. Its from near Grand Junction, Colorado. Its made of fine grained quartzite.
Heres a photo of another small knife from the same locality. Its made of chalcedony.
This is a photo of the reverse of the above blade.
This is a spear head or knife from western Pennsylvania. Its made from Flint Ridge, Ohio flint. The quarry at Flint Ridge has been in use for thousands of years for the quality flint it produces.
Heres a selection of various blades and scrapers from near Grand Junction, Colorado. The two bottom ones are made from a glassy quartzite.
