For me in modelling standard double edge bevelling holds up pretty well for either a standard edge or a sub D edge.

But it all depends what you are talking about as far as edges go, so I guess in this context, a surgical blade vs a metal table needs some entirely different geometry to give that detail.

I generally model edges in fairly hard and not use edge weights, so I guess I may not of encountered your own issue myself.
