The Leatherman Skeletool is currently available in several varieties, including the long-running standard model with an unfinished stainless steel body, a chunk of aluminum in the handle, and a 420HC semi-serrated blade, and the Skeletool CX variant with…whatever the black coating is made of, a carbon fiber chunk in the handle, and a 154CM plain blade.
When the model was first introduced, the base model had a plain blade, and the CX had a semi-serrated blade. This was swapped, as they realized first time knife buyers were more likely to see the semi-serration as a value-add, while more serious knife guys would prefer a plain blade. So you might find a very old Skeletool with a plain 420HC blade, or an old CX with a semi-serrated 154CM blade.
