Variations
In order to reduce weight, chains have been manufactured with hollow pins and with cut-outs in the links. A few titanium chains have also been made, but while much lighter they are vastly more expensive, perhaps 10x the cost, and the titanium bearing surfaces reportedly wear quickly, leading to shortened life and reduced efficiency.

Famous quotes containing the word variations:
“I may be able to spot arrowheads on the desert but a refrigerator is a jungle in which I am easily lost. My wife, however, will unerringly point out that the cheese or the leftover roast is hiding right in front of my eyes. Hundreds of such experiences convince me that men and women often inhabit quite different visual worlds. These are differences which cannot be attributed to variations in visual acuity. Man and women simply have learned to use their eyes in very different ways.”
—Edward T. Hall (b. 1914)
