I understand that.
You are all referring to the area under the bark, back and heart which are parts of the scrape I did not mention in my post, but I'd still like to see those scale CAD drawings!!
The point I was trying to make was, when you get to the extreme tip (the last 1mm or so) the cane is thinner than paper and of a precisely even thickness all the way across. Every reed-maker I know uses a flat plaque for this part of the scrape, at least!
So our scrape MUST have flattened out that "inner-spine" somehow, no? And the extreme center of the tip (widthways) will therefore be formed from cane that is ever-so-slightly softer than the rest of the 1mm of extreme tip. Possibly, even probably, the difference is infinitesimal.
When "finishing" a reed, I often end up dusting (literally) the tip to the corners, but straightening up off the end to prevent ripping the corner off. Perhaps this does impart extra strength (relatively) to the center of the extreme tip.
