I don't think having blocks of wood shown to indicate equivalent amount of wood for the weight is a good indicator or helps anyone who wants to reduce weight as obviously no one wants to cut off a block of wood to reduce weight. A more useful information would be to see if maybe 3 or 4 mm of reduction in thickness all along the blade - as to how much weight that would reduce. I have been able to reduce about 2-3 oz of weight in past by shaving off wood evenly all along the face of the blade and resulting in a few mm of edge/spine sizes reduction overall (didn't make exact measurements at that time to be able to post here). Same could be done by shaving off in back of bat but that is more difficult due to the curved nature etc. Best if one can get a batmaker/professional to reduce the weight by shaving evenly from the back.
Ahh my sincere apologies if my post caused any confusion on your part?
It was purely to highlight what a chunk of cricket bat willow that weight is
Sanding 3 to 4mm off the profile? Okay,,,, that’s a lot of sanding
Your basically changing the bat
Personally I reckon re do that toe, and see how that picks up first, then look at the rest of the bat
