Yes, this is a slide (sometimes called a bottleneck). They are usually glass, porcelain, ceramic, copper or steel. All these elements have different tonal variations. Most people play with a blade on a finger or ring finger (personally, I prefer the little finger). Most commercial slides come in various thicknesses, diameters and sizes - to suit your preferences sizes and finger. The old way of playing slide was cut to the top of a bottle of wine - hence the name bottleneck. glass slides for appropriateness in this way is the best in my opinion. There are also smaller type of slides that you can wear almost like a ring, and paper type or turn around when you want to drag the game Here's more information: http://en.wikipedia.org/wiki/Slide_guitar
