Lignum vitae sounds like just the ticket.
Surely you have or can get the trees I mentioned.
Where do you live?
I have ironwood (hop hornbeam) growing on the place naturally.
I brought in black walnut, Osage orange, black locust, red mulberry because they are rot resistant... think 30 year fence posts. I also tried planting honey locust without success.
Bummer if you haven't made room for this kind of tree.
No need to carry tree to lumberyard, I make handles with draw blade.
Re :
Old wheelbarrows...
Some were given to me, some were found on trash day, before the garbage truck got there.
Not saying everyone should be hoarders, but OP did ask what we were using.
