If I had a hammer...
I bet you have never had carpenters elbow?
You could be right. I have used it instead of shrink to hold a battery pack together and to repair a rubber ducky antenna on a wireless phone and for electrical insulation at wire junctions where shrink wouldn't work. I vaguely remember using it on a handle but can't remember where. It might have been a screw driver for a better grip. It sure is less messy than a dip and there is no dry time and if it gets a little messed up it is quickly repaired I never subjected it to a lot of abrasion. I once used as a dust cap on an open brake line. That didn't work out too well. There is something that unfuses it..... brake fluid.The self-fusing tape is not very durable as a handle surface by itself. Think about using the tape then plastidipping it.
What about tennis racquet handle grip stuff? Double wrap that and you'll be golden.
I sent a text to a co-worker that did the handles at the fire station today. His reply was that he used hockey tape like a few others mentioned. However one thing he also did was a spiral wrap of oxygen tubing before the hockey tape. This gives a little bit more of an edge to aid in the grip with wet gloves.
I have hammers of all sizes with the handles cut very short for clearance/restriction issues, up to 20lbs. Best thing to wrap the handle in is parachute cord in my opinion. Works better and lasts longer.

Do you glue it in place so it stays?
