Schulte Strathaus offers a cleaner that has a tension mechanism with a clock pointer and patented blade attachment which make maintenance easy.
Open the lever from the clock and take the segments off the drum. Segments are attached with clips so sockets or bolts or other easily jamming parts do not need to be removed. You still need to use your hands and as much as you like. The blade base is solid steel and no aluminum part are used…and will never be. This maintenance is also for the big boys.
