The ancient Neanderthalers used an advanced mixture of birch bark resin (extracted by heating birch bark in a closed container, i.e. no air to it) with ground charcoal. The charcoal resulted in a more rigid, non-flowing, compound about as strong as epoxy once it cooled. They used it to attach spear and arrowheads and flint blades into knife handles.

I'll be doing that if this lockdown goes into week 5 or 6
