(2007) We've been getting some questions on the shape of the new handle design.

Basically it's about 3/4" wider and 3/4" taller and the square base is gone; On the new design, it is easier for the plates to go up in between the handle's "feet" and more closely approximate a round kettlebell. Look at the right and see how the plates "come up" between the handle.
Also, the extra width helps out on two hands on one KB moves, and the extra height makes setup of a comfortable shape a bit easier as well.
