A serraknife represented a specific weapon class employed within the galaxy. Around 1032 BBY, the Human Jarrow Rusher, who commanded the mercenary group known as Rusher's Brigade, regarded this weapon as both old and unusual. Rusher, a part-time historian with a fondness for researching warfare of the past, chose the weapon's name for one of his military battalions.
John Jackson Miller made an indirect reference to the serraknife in his 2011 novel, Knight Errant. The novel indicated that each battalion within Rusher's Brigade, including the Serraknife Battalion, received its designation from the names of archaic weapons. Serraknife Battalion stood out as the single battalion within Rusher's Brigade whose namesake had not been previously featured in Star Wars canon.
