The present invention relates to an elongated device (10) for cutting media, the device having a centerline axis (C L ) along its length dividing it into first and second halves (10a,10b), the device comprising a handle (20) having front and rear ends, a head (60) extending from the front end of the handle, the head comprising (i) a cover (62) having a sidewall (66a) extending therefrom and (ii) a guide (80) disposed substantially underneath the cover and having opposing top and bottom surfaces, the top surface (81) being proximate to the cover, the bottom surface (82) being substantially planar, the guide further having first and second halves divided along the centerline axis, a first exit (88a) disposed on the first half (80a) of the guide and a second exit (88b) disposed on the second half (80b) of the guide; and a blade (100) disposed in the head and having a cutting edge (103) where a leading edge (102) of the cutting edge intersects the top surface of the guide at a first reference point, wherein a first line connecting the first reference point to the first exit on the first half of the guide is not parallel with the bottom surface of the guide, wherein a first distance (D 1 ), measured from the guide first exit normal to the guide bottom surface, is less than a second distance (D 2 ), measured from the guide second exit normal to the guide bottom surface. |
