Tom, splitting the wood for handles would be a good way, but generally I use a straight grained material and have wide enough planks, so with some searching around to find a fit, am able to saw out with the grain pretty close following the shape I want. I made this handle for my adze way back in the dark ages. Generally striking the wood askew, i find that the chamfered edges keep the tool from turning in my hand, as opposed to an overall oval shape. Made from Ash, strong but still fairly light.
