i heard about them this weekend and saw some of the bats online.

they look like fastpitch softball bats..

i haven't figured out if the end of the bat is smaller now or not and I also wonder if moving some meat towards the hands has improved the balance some?

years ago, i got my oldest one of those axe handled bats, cause he'd split some wood in his youth. Those felt good in my hands and I thought they helped keep the wrists parallel to the ground, at contact. The metal bats themselves, sounded dead to me. He used it one year, someone dented it and I got it replaced under warranty and then sold it to a younger kid. That was our experience with those.

we'll see how this experiment goes
