I have 2 kilt pins, one is the claymore and one is a family crest.. If we can get another 25 or so ordered, I can get an XMtheS pin too. I have found they do add a bit a weight to the edge of the apron and reduce fly-ups in light wind. I had always thought they were pure decoration, but the family crest is almost 2" across and it weighs at least 2 oz. and it has made a difference in the wind and helps kep control of the edge of the apron with little effort.
