The bit about the definition of a fixed crysknife in Dune: House Atreides doesn't necessarily contradict the main article's definition.  If a crysknife is keyed to an individual's magnetic field, separation from that person and the death of that person would both cause destruction of the crysknife.  Two different ways for the same thing to happen, not a contradiction. 23:54, February 21, 2015 (UTC)reader
