Mathematical formulation of razor grinds?

[ferroburak]

Hi,
Is there a mathematical formulation of razor grinds? The newly produced razors are shaped most probably on CNC or alike devices so I wonder how different blade profiles are formulated.

No, also the new produced razors are not shaped on CNC, please look this:

Thanks for the videos. Concavity of the entire blade is due to a huge hammer it seems

If they could be produced in CNC or in similar setup much cheaper they would be I guess..

Razor Edge Geometry Introduction over at Robert Williams Custom Straight Razors is a good post.

the grind is basically shaped by the different wheels held against them when ground. They are basically shaped by hammer etc, but at the end of the day it comes down to wheel sizes (though often, and especially on more hollow grinds, multiple sized wheels are used)
