The fine carpet tool is used on the likes of silk an viscose rugs. It has a fine external jet and the throat is angled for high air flow without wrist strain. It is fitted with stainless steel glides. I did make some nylon glides a couple of decades ago but they got burnt when my van was stolen in 2000. about half the contents were removed by the thieves before the remainder was fired. The stainless parts of this tool were found in the rubble.
