The holder comprises a tubular membrane (1) made from a flexible material, having end collars shaped to form lips (1c,1d) which seal against the surface of the tool (2) when in use. The membrane has an inner air chamber (1a) which is deformed when the holder is gripped, creating a vacuum which grips the tool. The holder is made from two layers of different materials - an inner nonporous layer which provides the seal, and an outer cellular layer for greater comfort. |
