Not that I am trying to let down your Joker bat as it surely looks like a master piece, but it just reminded me of a bat that owned last year.

Around 60 mm edges.
G1 Lush English Willow in 2.15... it had an eye popping pickup just by looking at the sheer muscle.
This bat would terrorize the fielders and bowlers alike, and send the umpire into a jaw dropping shock. Just look at with the BDM bat that had a quite thick edges.
