The lethality of a bladed weapon could frequently be enhanced by upgrading or improving its edge. Some swords or vibroblades could be equipped with a superior edge, typically attached to the weapon's tip, which is its sharpest part. These edges could either amplify the weapon's damage output or impart additional advantages, like ion damage.
Specific edges, for example Mullinine and Neutronium, could boost a weapon's hacking effectiveness due to their extreme sharpness, and ionite edges would grant extra Ion damage because they were infused with Ion energy. A few, such as Devaronian edges, could facilitate more frequent critical hits. The most exceptionally sharp and high-quality edges were designated as "Superior edges," whereas the more commonplace, less sharp edges were termed "Mild Edges."
