Can always tell when there has been a death in the family when trade specific tools end up on trade me or market place well under priced.What's interesting is that a lot of his manual tools would be over 60 years old and still better than a lot you'd buy today. I've got an old drill brace of his that he was given as a present when he left a farm he was managing so would be over seventy years old.
We had a builder doing some work at our place when the electrician wanted the power off and so the builder asked if I had a battery drill powerful enough to put a 15mm dia hole through a 100mm wide beam as his battery drill had run out of juice. He laughed when I produced dad's old drill brace with a 5/8's bit..... by time he'd finished with it, he wanted to buy it from me.
I've got a relatively new Stanley crosscut saw that needs sharpening every couple of years.... and dad's old Disston and Son's saw is nearly 70 years old and never needs sharpening.
Another spot is the old community markets you ask the people what the tool does and they don't know what it does so you can get them cheap there too.
