This will seem like blasphemy to some people and I have mental images of horn scales exploding and bone scales breaking and wood scales cracking and people crying and babies dying, but would it in theory be possible to forgo the whole washer thing and just pressure fit flush pins?

My plan is thus: drill a hole, say, 1/16". Take 1/16" pin material. Very very lightly sand or run over a finishing hone(to rough up the surface) Plunge in liquid N2. Insert through hole. Let warm. Pressure fit. Done!


Yes, I know very very cold can mess up the blade steel. HOWEVER... the heat loss would be equal to the weight of the pin times it's specific heat times the temp difference (m*c*dT) and so the razor blade would only be cooled by a little bit as its mass is much higher. AND you're cooling at the tang not the edge. AND heats dissipates through a piece of metal according to a sine funciton approximation- like a ripple. So by the time the heat sinking reaches the edge it will no longer be that significant. AND one could add a moderate heat source (match, fingers, warm water) at the shoulder to curb heat loss (cooling) at the edge.
