The currently in vogue hexagonal hammershank cross-section shape is not the best. In fact, it's not really very good at all. Many early action makers used a rectangular shape well out toward the end of the shank. Some of the Pratt-Read shanks we used in the 1970s started out with this rectangular shape extending out about 3/4 of the length of the shank in the bass, about half way through the tenor, and about 1/4 the length in the treble. Why this is no longer done is a mystery to me. I guess the idea didn't originate in Germany. Del Del The Abel shanks have gone to an all thinned shank.Though not the shape your are referring to they seem to be made of very stiff Hornbeam, I'm guessing now. What is your opinion of this. Mine is that it works well with modest hammer weights but now wonder at action saturation with heavier hammers. The last set I used was heavier than the octaganal shaped Renners. That's wood for you.
