Static blades

Blades are arguably the most used weapon choice in robot combat, not out of effectiveness or popularity, but out of flexibility, low weight and the ease of which they can be attached. Blades come in many forms; Spears, Spikes, or Moving Blades. In addition, blades of many forms were often used as extra weapons, such as Wild Thing's pointed lifting arm,, and the glancing spikes of Darke Destroyer 2.

Spears
Spears are the term used to refer to spike weapons that were used offensively. Best examples of spears are Tornado's static spike weapon, and the dual spikes of Spikasaurus, the annihilator champion. The difference between spears and spikes is the length, and that spears are meant for piercing robots internally, whilst spikes are generally just used to damage on other robot's exterior.
