This is something that nobody wants to think about, but when nobody is coming to take your dead away, you will have to do it yourself. When that happens, it would be nice to know things like, will you hit water at 42"....or 18"? Roots? Clay? Rocks? Maybe that grave site location is less than optimal. If you stick to the way we do it, with every adult male taking a turn at the shovel, it is still a big job. Break a handle on a root and it can become much worse. I'm a big True Temper fan. They're made in USA and come in shapes and sizes that work in my sandy, root filled ground. Their handles are okay now.... but looking long term, I'm swapping broken hickory for fiberglass. It's the coastal humidity that is the issue. I could do pine tar treatment on them and extend their life, but not as long as fiberglass. There is a little added weight, but that is useful in root cutting, and not near the strain that digging with a broken handle would be. Not a tool subject that's pleasant to think about. Even more unpleasant to practice, but comforting to master before it is necessary.
