Philosophy of a Knife is a 2008 Russian-American documentary exploitation horror film written, produced, shot, edited, and directed by Andrey Iskanov [ru].

During World War II in China, a Japanese covert division known as Unit 731 conducts gruesome experiments on humans in its research for biological and chemical warfare.

A selection of tracks named Choice Cuts from Philosophy of a Knife has been released as a limited edition double vinyl, plus a bonus CD by Spikerot Records in 2018.

The Worldwide Celluloid Massacre has Philosophy of a Knife listed as the fifth most disturbing film it has covered, and stated that while it was interesting and intense "I was reminded of Gibson's Passion in that the movie takes an ambitious and difficult subject, then spends most of its time focusing only on gore".

Congratulations are in order for Philosophy of a Knife in that it succeeded in being the crappiest pile of masturbatory, art-house wannabe, pedantic and mean-spirited shit I've ever had the displeasure of watching".
