Production hypothesis 1:
Step 1:
Making a block of maple in the shape of the hammer shanks
Step 2:
Cutting the single shanks, shaping to individual measures with a file and card scraper.
Result 1:
In principle it is possible to make the hammer shanks following this procedure but it is difficult to achieve the continuous decrease of dimensions in a controlled manner.

Production hypothesis 2:
Grading the shank in a box with a conical groove, by slight shift the differences in sizes of shank ends from bass to treble can be achieved easily and under control. After the right-angled grading only the edges have to be rounded and smoothed using scrapers.
Result 2:
Grading in a box permits a continuous decrease from bass to treble. The traces of this procedure are resempling those found at the original objects by using the assumed tools, hand cut files and scrapers.
