Why A Hammer Head Doesn't Need Glue

Ever wonder why old hammer heads never needed glue? In this one I walk through why a properly fitted hammer or axe handle relies on a wedge and compression, not adhesive, and why that method has lasted since the Bronze Age. I get into grain direction, why the head should slide on before wedging, and why glue can actually hide a bad fit instead of fixing it. Also touch on the difference between hafting methods used by early humans and the wedge system we still use today. If you've ever had a hammer head fly loose or you're rehanging an old tool, this should clear a few things up.
