Monomad: how much iron is often used?

Hello black and white.
How are you today, I hope you are fine.

On this occasion I would like to donate some iron objects that I photographed.
Such as padlocks and other tools.

I took several photos of this object with my cellphone.
With a black background.
Then I edited it into a black and white version.

So today I want to share this photo with friends.
Here are some photos as follows:

trouser zipper

Staples that are often used to go upwards are dislodged

This lock and key is used for purposes

I'm going to put this (how much iron is often used?) into a daily #monomad contest organized and curated by @monochromes

Thank you black and white friends who have visited my account, I hope you like it. Greetings from me @asklanbudi
