A silly topic - what's your Edge?

My first edge was a very RPGy ankh necklace. Then the hard acrylic vtes official edge, but that was too big and it irked me when people stood it on edge and it inevitably fell over.

Now I found this happy fang face button, snipped off the pinback and pulled it out with pliers. It now sits flat with a small tabletop footprint and still stands out while being easily transported within my bloodbank container, it's perfect!
