A couple of years ago I went to an estate sale, and was lucky to be one of the first there, the old Gent who had gone on to a better place left his tools!! I bought a Brace and all the bits he had, still like new, well cared for! bits from over an inch down to a 1/2.. along with a lot of old Ford pipe wrench's , well a 5 gal bucket full of that kind of stuff..$5.00 !! I spent 35 bucks there and my truck was full, some was boxes full of "stuff" that I just glanced at and they too turned out treasures... won't go into it but I think I figured out that an Estate sale is better then a garage sale... The shops and garages of old timers will have tools and things that aren't really available today...or are at big modern prices... People never fail to amaze me , a friend took his garbage to the dump and in the area by the gate where people set out stuff that others might find a use for he saw an old time carpenters tool box, wood, long enough for the longer tools, he thought waht the hell I take it, pulled over and it was ffull!! somebody had died and the kids didn't want the stuff..it had all his saws hammers , every thing to build a house the old fashion way... blew my mind!! even an old style plumb bob... when the SHTF, those old tools will be damn important!!!
