it and my own introspection ... It did not go smoothly, but if it went smoothly, it would be mediocre." Release In the United Kingdom, "Knives Out" was released on 6 August 2001 as the second Amnesiac single in three formats: two CD singles and a 12-inch vinyl single. It reached number 13 on the UK Singles Chart. "Knives Out" was covered by the Flaming Lips on their 2003 EP Fight Test, the pianist Christopher O'Riley on his 2003 album True Love Waits, and the jazz pianist Brad Mehldau on his 2006 album Day is Done. The 2019 film Knives Out takes its name from the song; the director, Rian Johnson, a Radiohead fan, said: "Obviously, the movie has nothing to do with the song ... That turn of phrase has always stuck in my head." Reception David Merryweather of Drowned in Sound gave the "Knives Out" single nine out of ten, praising Jonny Greenwood's "chiming" guitar for capturing the "romantic disappointment" and "wistful ache" of the Smiths. Reviewing Amnesiac for Pitchfork, Ryan Schreiber felt the guitar line was too similar to Radiohead's 1997 song "Paranoid Android", writing: "Great melody. However, they've fucking used it before." In 2010, Consequence of Sound praised "Knives Out" as one of Radiohead's "creepiest" songs: "It’s one of many tracks from the English quintet that tickles the bones rather than warms them. But that’s what makes Radiohead so unique." In 2020, the Guardian named it the 13th-best Radiohead song, writing: "The impenetrable Amnesiac debunked industry rumours that Radiohead were primed for a bankable comeback – but amid that album lay this meat-and-potatoes rocker, its scurrying riffs, mystic ambience and cannibalistic lyrics qualifying as glorious light relief."
