MD5 Jaws distances itself from the competition by combining our innovative JAWS groove design and perfecting the meticulous manufacturing process used to render it. The JAWS groove dramatically differs from the previous design in MD4 to promote significantly more spin and control. The walls, edges and angles are milled into the face with extreme precision to achieve the sharpest edges and tightest tolerances ever achieved by Callaway. The MD5 Jaws features our proprietary new JAWS groove designed to a 37 wall angle, an extreme difference vs. the 5 used in MD4. This elevates the groove-edge sharpness to a new level, for maximum grip and spin from all types of lies. JAWS grooves are particularly effective from 80 yards and in, producing a player preferred one hop and stop trajectory. MD5 Jaws also incorporates our proven Groove-In-Groove Technology. These milled Micro-Positive grooves are placed in the flat parts of the face for added surface roughness and grip. Three raised micro-ridges are featured between each groove, adding grip to the balls cover to increase spin on a variety of shots. This combination of JAWS grooves plus micro-grooves provides 84 different contact points to promote more spin. MD5 Jaws wedges lofted from 46 to 52 are slightly smaller compared to wedges lofted 54 and above, to create a natural shape-progression from the short-irons (8- and 9-) to the highest lofted wedges.
