If you've never used a saw with a mid-1800s or earlier handle, then it's hard to explain just how much better they are both ergonomically and aesthetically than a more modern handle. I used to think I had some fairly comfortable saw handles before I bought a pre-1850 Drabble and Sanderson panel saw.
It's true that some elements are purely decorative (the lamb's tongue detail where the bottom loop of a closed handle meets the cheek, for example), but some elements are eminently practical. The horns at the back of the handle embrace the hand nicely, and tell you when your hand and arm are in line with the cut, or not. On hand and panel saws, there's a notch on the top of the handle above the finger hole. When you use the saw two-handed, your palm sits nicely on the top front of the handle, and your thumb rests neatly (and comfortably) in the notch. (The same notch appears on some later saws, but smaller and consequently of no practical use - makers forgot why they were putting it there.)
Once you've used such saws, you find that the handles on modern saws (other than the very expensive top-end ones) are utterly dreadful both ergonomically and aesthetically. All I can suggest is finding some templates of older saw handles and making some new handles for your saws - adjust the handle sizes to fit your hand (a couple of practice pieces in something cheap will soon indicate what's best for you). You won't regret it - your saws stop being just a tool, and instead become extensions of your arm. You can use exotic woods if you like, but beech is just fine. It takes a lovely smooth finish, and three thin coats of Danish oil wiped (not brushed) on give surface protection but leave the handle feeling like wood, rather than the rather nasty heavy lacquer some tool manufacturers use, which just feels like plastic. Definitely worth the effort.
