Wolf-Garten multi-star® Joint Brush FB-M Hard for Weeds - Gentle on the Back! The new joint brush is a convenient solution for large paved areas that previously had no options available. With the unique click-lock mechanism, the joint brush can be connected to the appropriate handle from the patented multi-star® tool system in seconds. This allows for comfortable working while standing. The steel bristles of the joint brush make it easier to remove any weed plant. Large paved areas are a nightmare for anyone wanting to clean joints. Moss accumulates, and every single crack has to be scraped out. The work is done in a crouched position or on the knees, hour after hour. Thanks to the Wolf-Garten joint brush, that's now a thing of the past. Removing moss and weeds is suddenly as easy as sweeping the street. Joints are effectively relieved, as work can now be done comfortably while standing instead of laboriously sliding along the ground.
