My paper shredder motor had stopped working. Buying another one is costly. I was using it for shredding monthly bank statements as well as other mail with addresses on them.
I saw a stamp which will render text unreadable but it's not cheap either. So I decided to make mine for less than $2.00

The items required are:
1. white hi-polymer eraser (or any eraser with surface 65x25mm) from a stationery shop
2. a piece of wire about 10cm long and 1mm thick (2mm preferred)
3. a soldering iron
4. black ink
I chose black calligraphy ink, also from the stationery shop (ink $0.55, eraser $1.00SGD)
For inking I used a pep-bottle cap and stuffed it with a piece of dish-washing scouring pad. Dab the ink on the stamp before use.

Like will Red, blue or UV light make the "real text" stand out and not the stamped one?
Definitely saw a (fiction) movie where they did that, but I think they used something like this to read the "Dead sea scrolls" too.
