MECHANISM TO SEPARATE A WELL HOLDING TUBULAR, BLADE FOR USE IN A MECHANISM TO SEPARATE A WELL HOLDING TUBULAR, SAFETY VALVE FOR MECHANISM TO SEPARATE A WELL HOLD TUBULAR AND A MUPID TUBULAR. Comprising a mechanism (301) for separating a wellbore tubular, whose mechanism comprises at least one blade (310) for cutting said wellbore header, characterized in that said mechanism further comprises a projection (312). , in mobile use to reduce the structural strength of said wellbore tubular in an area where said wellbore tubular is to be separated.
