A multifunction straight edge guide having a handle and a straight edge. The handle has a plurality of perimeter surfaces and the straight edge has a mating edge to mate with one of the perimeter surfaces to interconnect the handle and the straight edge. The handle has three sections, two outer sections and a central support ledge. The outer sections define sidewalls which are generally perpendicular to the support ledge so that the straight edge guide can be used with either the left or right hand by turning the straight edge guide over. Each of the plurality of perimeter surfaces are angled with respect to the sidewalls.
