The Thor hammers were the #1 selling product of 2013 in the StrongerGrip line of Premium Strength Gear. The standard Thor and the Ultimate Thor both have handle sizes that make you scream to the gods after weilding them for a period of time. The Standard has a round 1.9" and the Ultimate has 1.9" but oval shaped on the gripping end, both are beastly.
The NEW Thor Hammers with comfort handle have the same handle as the intital line of SG sledgehammers, it is 1.5"(1-1/2") and oval shaped like all the sledgehammers. It is super comfortable and ready to bring you strength. The loadable head is 4"x4", overall length is 16-1/2" from top of head to end of ball on handle.
