Nowadays, these items such as bearings, wires knobs and clamps no longer considered only for men's stuff. Before, when dad took over mom's job such as cooking, taking care of the kids, laundry and other household chores give him an embarrassment having this feminine things on his hand. This becomes a common sight now in more household. Women, however do more masculine job like lifting, driving and more.
Let's face it! In some other cases where both men and women work, women tend to do more household stuff when they're both home, while men stop to work and rest in a bed like a king. It could be because when men were young, they were never brought up to be doing household chores while young girls were taught to master domesticated job and learn all these thing at a young age. Even if women weren't taught about repairs, replacing door knobs and all the supplies like that at Reid Supply Industrial that links to men's stuff, still they did not limit their capability into just baking a colorful sweet cupcake.
In reality, it is still a traditional role that women should take care of the family at home and equality seems to be far off in the view. This equality should then be raised from the time we were born in this world.
