I keep seeing people call any old stone tool a 'hand axe' and it drives me nuts
Specifically, I was at a museum in Albuquerque last weekend and the tour guide pointed to a simple flake scraper and called it a hand axe. It matters because a hand axe is a specific, bifacial Acheulean tool type, usually teardrop shaped. Calling everything that just means people learn the wrong thing. I learned the difference from a field school professor who made us sort lithics for three days straight. Anyone else run into this kind of mix-up at local museums or sites?
