There are a few spydies in my collection that are more special to me than the rest. I tend to carry those knives only on special occasions. This WTC memorial knife is one of them. Every 9/11 I take it out of its wooden box, wipe the protective grease of the inlay and blade, shoot a picture of it and clip it to my pocket for EDC.
