Pictured is a handle grip I welded from scraps when the plastic grip on our snow shovel cracked and fell off of the wooden portion of the handle. This Instructable will detail the process of making a new handle grip. A welder is required.
The piece inside the yellow lines is 3/4 wide and 1/8 inch or slightly more in thickness. It is 11 inches long. The size of your hand will be a factor, but I bent this one 3 inches from each end, leaving 5 inches across for the width of my hand.
