 The Oboe BBoard

A repairer I used to know, trained in making period instruments corroborated about wood cutting what my late brother taught me about cutting high-density metals. There are 2 angles between the bed (cane) and the blade: the top of the blade and the bevel at the bottom. Both affect not only the shaving, but the pressure put on the material (cane) and the "dig behaviour".
The smaller the cosine between either blade surface and the bed, the less vertical pressure and less dig. The top blade surface controls the dig.
The geometry of cutting is a HUGE area for mathematical and physical study, so I guess anecdotal experience will have to suffice.
For sure, the shape of the blade relative to the curve profile changes the profile of the cane and thus how one scrapes in the end. I tend to think less scraping is better, but its not as simple as that.
