Stunning set of 10 sunstantial crystal knife rests. They catch the candle light and sparkly gloriously. 
Porte coureaux or knife rests are used to avoid French table manner faux-pas, to keep the table linen clean and of course to be decorative.
There are some nibbles to the glass as they have been used regularly to grace a Château style table setting and is a sign of their age and importance in the lifestyle of their original owners.
