Topic: Small glass pillars - what are they and what are they for?

[Shinyglass]

A question from a friend at a shop, so not my glass, but I'm baffled too.

These are two identical small solid glass cylinders with rounded ends. They narrow towards the middle, and have a hexagonal profile so they can stand on their sides, and narrow. The ends are rounded, but have star-cuts so they can stand upright. There is severe wear to them, and they have no visible maker's mark. The sides of each cylinder alternate with toothed patterns and cross-hatching. They are each about 3-4inches long and just under an inch wide at the widest.

The maker would be great to have, but does anyone who what these are for? Our guesses have been everything from curtain weights and pot holders, to chopstick stands so far, and I'm stumped.

(I've asked for more photos, so they should follow shortly)

Knife (or other cutlery) rests I think. These are pressed glass one http://lustrousstone.co.uk/cpg/displayimage.php?pid=2012

Thanks. I had a look online at cutlery rests, and I think you are right. Going through the books, the cut looks like Clare by Waterford, but without a maker's mark it is hard to be sure.

Knife rests seconded. 
They can come in many decorative forms, not all are made from glass.
