Abstract
Safety cutting blades and utility knives having such blades are presented. Safety cutting blades include safety features that protect users from contacting a cutting edge. Preferred blades comprise a stem and a cross bar that orthogonally intersects with the stem. One or more cutting edges can be disposed within a notch made into an edge of the blade. Safety features can include safety guards located at one or more ends of the cross bar where the safety guards cooperate with the stem of the blade to form the notches. The notches can be sized and dimensioned to reduce a risk of a body part from contacting a cutting edge.
