Specialty machines are machines that do not fit into one of the other categories on Hingmy. They can be combo machines that do multiple machine steps at a time, or true unique machines.
Specialty machines can only be compared based on general properties such as physical dimensions, weight, and power. If we find a cluster of machines that match eachother closely, we will create a new category for them on Hingmy.
Specialty machines are hard to compare, because there are so few that do the exact same thing. Each machine is unique and should be evaluated as such.
