Switchblade was formed by guitarist Andrew Najdek, drummer Mat Piccolotto and bassist Ben Bessant in 2001. The trio spent the better part of their final high school years playing metal cover songs and writing a handful of originals which would become early Switchblade demos. Vocalist Chris Apps joined the band prior to the recording of the band's very first demo, but split from the group directly following the recording. In early 2002 Switchblade recorded a new and much heavier demo and began to audition vocalists. The auditions were unsuccessful, and the group struggled to find a frontman until Piccolotto answered an internet messageboard post by vocalist Colin "Sway" Druery, who shared a similar musical vision and joined the band in 2002. Switchblade began working together on original material, however only a few short months into rehearsals, Sway would permanently damage his vocal cords and was forced to leave. Switchblade was once again looking for a suitable frontman. During this downtime Najdek began using a seven-string guitar, and tuning much lower than he previously did. As a result of this the band's musical style moved away from its thrash metal and death metal core and took on a much more groove metal approach, similar to bands like Pantera, Machine Head and Fear Factory.
Switchblade again found themselves recording another instrumental demo at the end of 2002, the first of the new material written completely on a seven string guitar. Sway got a copy of the demo and was compelled to return to the band. Inspired by this new sound, Sway quickly wrote lyrics for the new Switchblade material, recorded his vocals on the instrumental tracks, and Switchblade's 2003 demo Incoming was released in early 2003. Switchblade then began doing the rounds on the Sydney metal scene and was soon touring interstate and supporting higher profile local bands like Daysend, Sunk Loto and Dungeon. Meanwhile, Piccolotto also briefly joined local thrash metal band Descend, who disbanded shortly after, and Najdek became a member of local power metal band Friar Rush.
In mid-2004 the band realised its musical output was limited by only having one guitarist, so a second guitarist was added in Scott Bernasconi, who played his first show with Switchblade on 19 June 2004. The band's material was re-worked to make room for a second guitarist. Soon after, Switchblade played a string of shows with now Los Angeles based tech-metal outfit Devolved, Sydney band Daysend, and Machine Head. Switchblade then booked themselves into the studio to record their debut album with Astennu producing.The End of All Once Known was released on 12 March 2005, showcasing a more melodic and technical approach than previously. Switchblade then began a series of shows around Australia to support the album, but Bernasconi and Sway left the band after a final performance Sydney on 29 October 2005. During the final song of the set, Sway was joined on stage by a good friend of the band, Adam Helmrich, who was asked to join Switchblade almost immediately.
Following the departure of Sway and Bernasconi, Switchblade took a break to focus on finding a second guitarist. With Helmrich already confirmed as new vocalist, Anthony Delvecchio was announced as the new Switchblade guitarist in early 2006. The new lineup was then booked to make its first appearance at the annual Metalstock Festival, held in Scone, New South Wales over the Easter weekend. Two weeks before the show Bessant relocated to Perth and cut off all contact with the band. Symon Alhaddad, guitarist for Sydney death metal/thrash metal band Vaticide temporarily filled in on bass guitar, eventually joining Switchblade permanently. With the band's lineup now solidified, Switchblade went on to play a number of key local shows including the 2006 Come Together Music Festival, and a show at the Marquee, Sydney, which was filmed and recorded for a future live DVD. The band ended 2006 by appearing at Metal for the Brain and then supporting Nevermore in Sydney on the same day.
At the start of 2007, Switchblade had originally planned to cease all live shows however they were then offered the opening spot on a tour by Trivium. To capitalise on this appearance, Switchblade then played some tour dates around the country and featured on a national touring metal event billed as the Festival of the Dead. In 2008 Switchblade opted to put all live shows on hold and focus on the writing and recording of the new album. In a 30 July 2008 MySpace blog, Switchblade revealed the title of their follow-up album to be Invictus Infinitum. They also revealed that Alhaddad would be leaving the band, replaced with Gerard Dack of Infernal Method.
Invictus Infinitum was released in Australia on 6 June 2009 on Melbourne-based label AmpHead Music, and was supported by a national tour which included shows with Psycroptic, The Amenta, Daysend, Alarum, Frankenbok and many more. The album was mixed by Grammy Award-winning producer Neil Kernon in the US and featured Nevermore guitarist Jeff Loomis on the track "Reflective Curse."On 15 October 2009 Switchblade capped off a massive year by supporting thrash metal band Slayer, for their one-off Australian performance of the seminal album Reign in Blood. It was also announced that the band would be supporting the newly reformed Wollongong-based band Segression, who were one of the most prolific Australian metal bands during the 90's, but had broken up in 2002.
