A portable motorized cutting tool has a motor housed in a tool body, a cutting member, a transmission linking the motor to the cutting member, and at least one guard for protecting the hand of the user, providing a passage for the hand around at least one of a control member of the tool, and a gripping handle of the tool. The tool has a cover capable of occupying a so-called “closed” position against the body of the tool, and a so-called “open” position separated from the body of the tool and giving access to a part of the tool protected by the cover in the closed position, the cover being linked to the body of the tool by the guard.
