This ascot stickpin is exactly that. A metal 'stick' with a small raven skull adornment at the top and a 'clutch' at the bottom (to keep you from poking yourself and to keep your pin secure). It's one of the oldest styles of pins there is, often worn on lapels, ties and lady's hats. It is very well suited to ascot wear over a tie tack or other style pin, because the long 'stick' helps keep the entire ascot secure, and the two flaps of fabric from separating while being worn. It also looks fairly deboinaire while doing so. 
This little raven skull is made of solid sterling silver and only measures a shade over 3/4"long. It is securely mounted on a 2.5" ascot pin with matching fitted retaining clutch that contains the sharp point.
