One of the few Trades a married woman could fully inherit her Husbands / Fathers or Uncles business historically was Blacksmithing, and you could get trained in it as a young Girl without question if you had family in the trade, this wasn't universal but in England, Wales and parts of Germany it was common, but in places like France, Spain, Italy and Scotland (highlands it was variable through time and location but in the lowlands it wasnt the case) it was nearly totally forbidden for them to do so.
Some female Smiths where immensely talented and sort out by some looking for particular work to be commissioned particularly for Doctors who where having custom medical tools made.
Oddly enough if you ever use or see a File or Rasp made before 1930 but not by a Smith for his personal use it was likely made by a woman doing piece work from home or her and her Children, it was a nice low impact job you could sit down on a stool to do and you'd earn your family quite a bit of cash doing it as while it could be done by machine and it is today back then it was considered cheaper and better quality to have it done by hand.
Same goes for Auger Bits, the initial factory edge was normally done to the blanks by a woman working from home.
God that takes me back, Me and my Dad where there the Day before about 100ft from where the Bomb exploded and we where planning on going the day it happened but decided to go early to pick something up because we wanted to go Fishing the day the Bomb exploded, I know it wasn't exactly a close call but whenever I see those pictures it sends a shiver down my spine.
