How To Improve Your Kilt Pins

[Kalok Sundancer]

I have bad experiences with that kind of pins. The disk that should hold the pin often fall off, and the pin disappears. I have tried to tighten the spring and cut the tiny groove a little deeper, but I am not succeed. Do you have some good advices?

I have two types of "locking" fasteners for those sort of pins. One is kind of a "pull to release" sort of thing and the other actually uses little hex-key type screws that are screwed into them to bind them tightly to the pin itself.

I got them off of eBay in bulk. You might look into those.
