Waterproof extra strong bond epoxy. You know the one you see in the commercials where they hang Granny up against the ceiling. You get the idea. :)
Not all of them. This one was in real bad shape. I guess the water and humidity that crawled between the original tang covers during all these years must have slowly rusted the steel.

Thanks to everyone else for the nice comments.
