Custom Killing is the fourth studio album by the Canadian speed/thrash metal band Razor. It was released in July 1987 by Toronto based label Fringe Product. It is more of an experimental approach and was fairly overlooked upon its release. It also features "Survival of the Fittest" and "Last Rites" which are the band's longest songs ever recorded. It is the final album to feature Mike Embro on drums and Mike Campagnolo on bass (until his return on the 2022 album Cycle of Contempt).
