Eid Longhi Anticlastic Stakes are designed in the USA by leading anticlastic practitioners Cynthia Eid and Betty Helen Longhi, these stakes are specially designed with steel side pins and bracing bolts to sit in your vice without twisting or slipping. They are machined from Delrin which is tough enough to form almost any metal and yielding enough not to mark silver. The steel bracing bolts can be reversed, allowing the stakes to be turned over in the vice. Medium stake: 11" long and 25mm thick with 12 bays from 9.5 - 200 mm diameter. Useful for bracelet sized work.
