Lovely discussion... And very interesting having watched you make one for me and having now had a go myself. In both cases, the wood was pressed by experts in the field. One by you and one by Matt H4L. You shaped one with me there and positioned and balanced the bat to perfection, positioning the sweet spot to within a micron. Mine? Well the sweetspot is roughly in the right place, but the shaping isn't anywhere near as well managed and the vibrational control is noticably different away from the sweetspot.
What do they both have in common? That when people use them they say of both "Wow, what a great sound!" and are impressed with the performance. I have made a sledgehammer, where you have made a surgical hammer, but both work. But I'm rambling.
I think that with an expertly pressed willow lump, as per Norbs comments, anyone can shape a bat, but not everyone can make a good one!
