This is a "stubby" polished copper guitar slide, perfect for grinding out some gritty old blues on your slide guitar, cigar box guitar, lap steel or whatever you like to play with a slide. The slide is 1 1/2 inches in length (plus or minus 1/8 inch), and the inside diameter is 13/16" (.812"), which will fit over the first knuckle on medium-sized ring fingers. These slides have been carefully buffed and polished to a satin or semi-gloss finish (a mirror finish would just get scuffed by the strings anyway when playing), with a special metal polishing compound that leaves behind a protective film. However, with use and wear this natural copper will dull and tarnish - but it is easily buffed and polished back to a nice shine using a number of old copper-polishing folk methods. The ends of this slide have been carefully smoothed and polished as well to make sure playing with them is a comfortable experience for the user. We include a square of self-adhesive faux moleskin with each of these slides for use in sizing the inside of the slide to your finger. This along with our glass vial slide makes a nice set to give you an idea of the range of tones and sounds that are possible with different slide materials.
