The way the Ratchet & Clank wiki capitalizes words has changed; therefore, this article should be checked, and, if necessary, capitalization should be fixed.
The Cesium Blade Edges caused the Buzz Blades' and Doom Blades' saws to bury themselves into its last ricocheted target (e.g. a wall or an enemy) for a second, then detonate, causing damage to the enemy it was embedded in. It could detonate in a wall but would only damage an enemy if they were close to the wall. This mod was especially useful as the Buzz/Doom Blades used a lot of ammo before it killed an enemy, as this mod could increase its damage and probably kill an unlucky enemy that had a saw embedded in them.
