The word "knifer" is not a standard or commonly used word in English. However, if we examine its spelling using IPA phonetic transcription, it can be understood as /ˈnaɪfər/. The "k" at the beginning of the word is silent, so it is replaced in the phonetic transcription by a schwa sound "ə". The "n" sound is followed by a long "i" sound, represented by the symbol "aɪ". Then, the word ends with an "f" sound and the schwa sound again.
