Most axes are poor splitters, that's why they sell mauls.

I couldn't say how the Estwing handles, they are new this year, and not too many of them out there to get any feed back. As for steel handles, it's a matter up to the individual. Most of my striking tools have solid core fiberglass, they do just fine. The one steel 12 pound Monster Maul gave me no trouble because it was steel, the main problem was being too heavy with too short a handle. I could split more longer with the Vermont 4 pound.
Velocity has a lot to do with splitting, too. In ballistics, a small fast bullet can hit just as hard as a big slow one. With a striking tool like an axe, you can accelerate the head even more by stopping your swing just level with the strike point, which accelerates the head. It's exactly the point of golf and baseball. You swing and snap it.
Estwing doesn't make junk, plenty of fans like their other products. Perhaps if someone would purchase the tomahawk and try it out, we can get an impression of it. There's just one catch, however - the results only relate to other tomahawks, not splitting mauls or axes. Hawks are different, just like a pick mattock is different from a standard pick. But it also hoes better than a standard pick, too.
Back on topic, I've come to the conclusion that True Blue is likely the best outdoor tool color of all. There's reasons for it - it's an obvious color which doesn't hide it, there is very little like it in nature to blend with it. Yellows can get lost some times of the year in a flowering field or falling leaves, oranges and reds the same. The public image of blue is utilitarian and friendly - not aggressive, machismo, or warlike. You are not trying to "hide" in the woods, therefore you are there for a reason, and it's not tacticool or potentially dangerous. True blue isn't something you associate with weapons, exactly the opposite.
I went camping one spring, the guys had built a campsite on a river island under a bluff. Hiking to the top, we reviewed the various shades of tarps, tentage, and ramshackle shelter we'd put up in terms of concealment. The wood and vegetation hut was nearly impossible to see from up there. The red camping tent also well hidden, even tho it was still early spring. The blue and white truck tarp stood out like a bombing target, and could be seen for a mile. Later we read up on the existing literature of the day and found red was actually a good color to use when needing to be hidden against green. It receded into the scenery and blended well. No argument from us, we'd already observed it ourselves.
In the Pantone system it's #255 or thereabouts, not dark at all, and quite visible. Plus, if you are color blind, it's usually still in your range and you see it. I like orange too, but blue does the job.
