Thanks. Limited metal work would have been more accurate.
Yes, I think so. Don’t discount the copper, gold, and other nonferrous metalwork of the tribes in Central and South America, either. Most of it boiled down to available resources, and for much of North America those were quartzite, some form of cryptocrystalline quartz (flint, chalcedony, agate), obsidian, rarely rock crystal quartz, or even welded tuff (seen in Nevada), so at least for projectile points, scrapers, drills and knives (pre-Columbian), stone was the dominant material by virtue of availability.
