The Waveblade is a melee weapon of Kexs design. Built specifically to cut through even the toughest armor, the Waveblade oscilates at an extremely high rate (giving it a distinctive hum sound). This exponentially increases its cutting abilities.
Waveblades are typically about 3 feet long (with a cutting edge of 2.5 feet), though they come in a vast variety of lengths and styles. They have entirely rendered conventional bladed weapons obsolete (even among other races). Some blades are even serrated, giving them a "chainsaw effect", making them more effective when used against flesh. They are universally activated by applying pressure to a band around the hilt, and dropping it (for example) will turn it off.
Outside of combat, Waveblade technology has been used extensively in mining operations.
