Kitchen knife

A kitchen knife in a dream is the dream's image of a tool of preparation whose edge requires constant attention. The knife is not a weapon by intent; it is a daily implement that is dangerous if neglected. The dream brings the knife when something in your life — a judgement, a piece of analysis, a critical faculty — is being used to break larger things into manageable pieces. A kitchen knife sharp and used cleanly is the dream affirming the tool. A kitchen knife gone dull and slipping off what it tries to cut is the dream noting that the edge has not been maintained, and the tool is now more dangerous than when it was sharp.
