Many would agree that a two man saw handle without a wing nut on the back is an improvement. After a few hours of sawing firewood I came close to forming a blister at the base of me thumb and I'm thinking that the standard handle just does not fit the hand correctly. The saw I was using is relatively heavy and filed quite aggressively. The saw cuts very well but this makes it very sensitive on the hand position on the handle. The main push/pull hand must be placed low on the handle to prevent the saw from catching on the push stroke and this position also helps the saw bite into the cut on the pull stroke.
The idea of making the saw handle that fits the hand is not new by any means. Normal D handled saws fit quite well and some modern racing saw handles are angled on the bottom part to fit the hand better. So I kind of took a hint from the racing handles and modified a vintage Sells handle to fit the hand better. I used a bone dry section of vine maple that happened to have a natural bend that closely matched what I was looking for. Since it is important that the hand does not turn in the metal fitting of the handle I formed the wood part very closely and hammered it in tight. After it was in place I added some ethylene glycol around the handle and in a small hole through the center of the handle to swell the wood and prevent it from working loose.
