If we go by the types available on melee weapons in the pedia we have daze, cutting, concussive, bio, laser and plasma. that alot of vagueness about the term melee.
However, The types in the engine are not what's mostly displayed in the pedia entries. Dioxine's terms are generally better in clarity for reading and the feeling of the weapons they are attached too, but they are not the same as the in engine strings and references. In engine cutting=melee iirc.
We also know bio bypasses all shields.
So that entry should probably say something "...concussive, cutting, (and daze?)"
