As mentioned in my previous post, I am planning on building a bread
cutting board.

Obviously, I need a waterproof glue but I'm not sure which glue gives
the best performance in terms of long-term strength, water-resistance,
and non-toxicity.

I am leaning towards using epoxy (West Systems) but am also considering
other watherproof glue choices like Tightbond III or polyurethane glue.

Any suggestions regarding pros/cons for this application?

Thanks
