I have never actually seen a crossection of one, all the pics on the internet are square on... so you are saying that it is thicker toward the tip?
Some I have seen are diamond shaped, others have a distinct "spine" like ridge running down the center and others are just round, as with ball headed warclubs I think a lot is open to artistic license. Speaking of which I just got another club carved, will have it done soon, this one is kind of evil looking though, didn't intend it to be but it has that "black knight" look to it.
The paddle was picked up and payed for today,
I'm gonna miss the little guy... Of course I now am $125 richer...
