I have found a real problem with rare earth magnets as Kilt Pin fasteners.

I get my rare earth magnets from old hard drives. Two alone are enough to hold a Kilt Pin so hard that it is actually difficult to seperate them.

However, they are magnets and seem to catch onto everything Steel and Iron you walk past. I have had them latch onto the fender of my car, a sign post, the counter at the coffee bar, my tape measure in the shop, my sewing machine, the refrigerator, the dogs water bowl, etc,

I've looked down and found pins, nails, and screws stuck to my Kilt Pins. I've had them yanked off and stuck to all sorts of things that I have walked by.

But the most embarrassing moment came when I bent down to measure a customer and the little steel tip of the tape measure around my neck stuck to the magnets and lifted my Kilt when I stood up.

I advise caution with using rare earth magnets on Kilt Pins.
