Both the Mueller 4-stage and the Zwilling 4-stage manual sharpeners feature a strong and sturdy build. However, the former offers better balance and stability during sharpening thanks to its broader base.

Note that while both sharpeners have four sharpening slots, the Mueller actually reserves three for kitchen knives and the remaining one for scissors. The Zwilling, meanwhile, assigns two slots for each type of knife, namely, standard and Asian.

Neither offered a particularly well-rounded performance. The former was quick and capable, though it was also rigorous on the knife’s edge. The latter produced a smoother edge but took too much time to sharpen. 

All in all, the Mueller is the better choice because it’s faster, more effective, and easier to use— and that is what’s most important in a convenience sharpener.
