Vintage Set of 8 Art Deco Czech cut crystal retailer Knives Rest

These date from the early C20th and are handcut and hand finished. Each is very slightly different. These are estate finds and do have some surface markings retailer and tiny fleabites, some caused during the original hand faceting and polishing processes but from also from being used. They are really in great vintage condition.
Approximate measurement 3 1/4" long x 3/8" wide.
