Magnetizer/Demagnetizer

From the website:

Magnetizer/Demagnetizer

One of the most useful items I have in my "bag of tricks."

We've offered this for over ten years and it continues to be a popular item.

For times when I want to have my screwdriver magnetized so that I don't drop a precious fastener down where I can't reach it.

I also like to magnetize my files so that iron filings don't get into places they're not supposed to be (oil lines, etc.).

Magnetize and demagnetize screwdriver blades, tweezers, etc. with a quick pass through the openings.

$8.99.
