Remember to forget me!
This all started with claims of forces pushing the blade away from the cap. While we do not have anything like agreement on what those forces are, we do seem to have a broad conceptual agreement, and progress towards understanding what kind of elements might contribute towards that force.
While Grant does his thing, I'll have a look at the other side of the assumption. I'll explore what forces are acting to keep the blade in contact with the cap. This will be somewhat simplistic, as I won't be factoring for the cut outs at the centre of the blade, but a standard beam deflection calculation (transposed) should tell us how much force is needed to bend the blade to the arc of any given razor. I can get some rough measurements off a Jagger head so there is something reasonably common to base an example on.
This should (hopefully) tell what force is being exerted upwards against the cap at either side, and how much force skin and everything else would need to exert to shove the blade off the cap. I'll put the formulas here too, so anyone can scrutinise this in case I have transposed it incorrectly (which is quite possible - I'm out of practice). If anything is unclear, give me a nudge and I'll try to simplify it.
