"The Jackknife from Art Glass is a straight cylinder bong that has been folded back midway up the shaft before setting during its creation, so the top half is inclined toward the hitter of the bong. Ice cubes can also be added and will catch at the jink.Art Glass Bongs are good quality glass water pipes with extreme functionality featuring both timeless and creative designs. Their average glass thickness is 3.2mm which is the same as the standard Little Sista made famous by Roor. Comparable in quality to any of the more famous brands, this Jackknife is a fraction of the price."^^<http://www.w3.org/2001/XMLSchema#string>
