The rotary trimmer with switchable blades of the present invention comprises a base with end retainers moveably supporting a rail, and a cutting assembly disposed on the rail. The cutting assembly includes a switching mechanism to switch between different blades by turning a switch knob accessible outside the housing containing the switching mechanism and the blades. The different blades can have different cutting edges such as a straight, patterned, scalloped, pinking, wave, perforating, or zig-zag edge. Turning the switch knob rotates the desired blade into radial position and locates the desired blade axially over a cutting strip. A clutch engages the switching mechanism during cutting to prevent rotation or axial movement of the switching mechanism.
