[origin: WO9840227A1] The invention relates to a letter opener, especially a manually operated letter opener, which is able to open a standard letter without producing waste. To this end the letter opener comprises a circular knife (3) mounted between two rails (4, 40) and pretensed by spring (7). The diameter of said knife is slightly smaller than double the smallest possible distance between the knife axis and the surface (1) supporting the letter.
