Chinese Shovel Repair
My Grandfathers hand-plow has had the tip brazed 4 or 5 times, by the look of it. It is a $30 dollar plow, but thirty bucks in 1935 was a pretty serious deal. He used the same plow to run 2 acres of vegetable garden up until he died in 1998, and I use it still, although it is due to be re-brazed (Texas dirt is a lot harder than Mississippi dirt).
I also still use Pawpaw's axe, which has had the handle replaced 3 or 4 times, and has had the head replaced at least twice since he bought it in the 1920s.
